I'm definitely going with Gyou'Un Sama lol. Why not, we need more Kingdom discussion up in this bitch lol.
So, on top of the stuff
@Owl Ki posted, there are plenty of reasons to believe that Gyou'Un was martially above Ren Pa, which we can get into right now. But first, let's address some things:
I think Renpa is the strongest all rounder general in Zhao's history despite Gyou'un claiming that Riboku was the "strongest" of all time.
I happily live in denial if it's for the GOAT
In terms of versatility, Ren Pa may very well be the strongest Zhao General of all time lol. Man could do everything.
He was capble of forming Grand Strategies for Campaigns as he was personally trained in tactics and strategy by Gen Po, who Ren Pa himself stated was capable of serving as Zhao's Shou Hei Kun (Commander in Chief of the Military), and yet Ren Pa's strategic ability is so great that at San You, Gen Po didn't even touch the grand strategy of the battle, Ren Pa forumlated the entire thing by himself lol.
Ren Pa was also, some freaking how, both a Strategic and an Instinctual General with a literal Photographic Memory, who dismantled Mougou's fortress
specifically designed to counter Ren Pa after studying him for a life time, using his Photographic Memory and his Instinctual Prowess.
And of course, as Ren Pa himself states, his Body was forged from 40 years of fighting on Legendary Battlefields against Legendary Generals.
Not just for Zhao, Ren Pa may literally be the most versatile General in all of Kingdom, with his only real competition for this title being Ou Ki who was similar to Ren Pa in the sense that Ou Ki could literally do anything on the battlefield lol. But let's get one thing straight:
Versatility =/= Personal Fighting Strength
This is something we all know. Ren Pa has arguably the greatest Versatility in the Manga, but this does not mean he would actually beat someone like Gyou'Un in a fight.
I was planning on addressing some reasons people say Ren Pa > Gyou'Un but most posts on this thread are very vague and no one really states why they think Ren Pa would win this really lol. So I'll really just say one thing:
"Ren Pa is one of the Greatest Great Generals of all time, of course he would defeat Gyou'Un in a fight"
The fact that Ren Pa is a Great General does not automatically place him as being a stronger warrior than Gyou'Un. As I stated above, Ren Pa is known for the fact that he is amazingly
versatile, and sure I'd place him as a top 10 Warrior in the Manga from everything we know about him, but the fact that Ren Pa made it to the rank of Great General does not in and of itself place him above Gyou'Un. Rin Shou Jou himself was Gyou'Un's own superior and a Great General himself, but if it ever came down to it, Gyou'Un would murder Rin Shou Jou with ease, as Rin Shou Jou was referred to as Ren Pa's equal as a General
despite having zero fighting ability himself:
We will get to some reasons that Gyou'Un seems stronger than Ren Pa to me in a second, but first a few more things:
There's absolutely no narrative reason for Renpa's retreat after having his blade reach Mougou's neck other than plot convenience.
I disagree with this as Ren Pa explains the reasons for his retreat in detail, those reasons being that Ou Sen and Kan Ki had essentially check-mated him, and even if he would've slayed Mou Gou it would've been pretty much impossible for him to defeat those two under the circumstances presented lol. Just a brief point there. Anyway,
i don't necessarily think Renpa is the only capable offense in his army but he's not only the vital offense either, just because he has some pretty damn OP vassals doesn't mean he's not the main attacking force.
The only Campaign that we actually saw Ren Pa participate in in detail is San You, so I can only talk about what we've actually seen from him in action. And in San You, Ren Pa did not make a single move from an offensive perspective that did not rely on sandwiching his opponents alongside his own Heavenly Kings.
Ren Pa made exactly two offensive moves at San You:
1. The move to slay Ou Sen
2. The move to slay Mougou
The first move revolved around Ren Pa and Kyou En together attacking Ou Sen at the same time, and the second specifically revolved around
both Rin Ko and Kaishibou striking Mougou's HQ at the same time that Ren Pa himself did.
Ren Pa literally meant to have himself and two other of his Heavenly Kings strike against Mougou at once and crush him in overwhelming fashion, not to hit Mou Gou by himself and decide the vital clash against Mou Gou solo.
Notice that this is fundamentally different from what Ou Ki did against Hou Ken and his army, Ou Ki specifically sent Tou off to slay Chou Sou while Ou Ki faced Hou Ken on his own. This is not the first time that Ou Ki himself seems to personally attack Great Generals by himself, as Ou Ki seemingly ended the Battle of Chou Hei by himself:
So there is basis in the belief that Ou Ki himself
was the vital offensive force of his own army, while Ren Pa seems to be more strategically focused and relies more on the momentum of his own Heavenly Kings in War.
At least, from the like, 4 days we saw of Ren Pa fighting lol. Things could be different in different scenarios but I can only comment on what we have.
Genpo compared Kaishibou's destructive capabilities to Renpa, but Bananji's arm strength was also compared to Kaishibou. Regardless of these claims, Renpa was still shown to be superior to someone who is physically more powerful than him (Mougou).
You brought up another point that I was planning to bring up myself:
That Ren Pa has explicitly been stated to be in the same Strength Tier as Kaishibou and Bananji. On multiple occasions.
Now, I know people on this forum reject this claim even though it's been stated repeatedly, but I don't lol. As far as I'm concerned, Bananji = Kaishibou =< Ren Pa as warriors.
Okay, so keep that in mind as I start to talk about Gyou'Un and why he was probably above Ren Pa in strength.
The first thing to note about Gyou'Un is his sheer hype.
Gyou'Un was explicitly referred to as "The Martial Might of Zhao",
in an era where Ren Pa was an active Great General and should've been in his physical prime. There is no way to rationalize the fact that Gyou’Un received
explicit Martial Hype above Ren Pa while still believing that Ren Pa is the stronger warrior.
Furthermore, Shin directly compared the weight behind Gyou'Un's blows to Gai Mou himself:
Another explicit confirman that Gyou'Un's blows are just as mighty as the Great Generals (and Gai Mou himself is a Great General who seems to have no abilities in warfare whatsoever aside from just being an absolute colossus of a warrior, and this is the man Gyou'Un was compared to).
Now, you might be thinking to yourself that the strength of Gyou'Un's blows might be on par with Great General Gai Mou, but that Gai Mou outclasses him in skill and thus Ren Pa would too, but look at what Shin says about Gyou'Un in the bottom right panel here:
Gyou'Un is "damn fast" according to Shin, and this is hype that even Gai Mou did not receive from Shin. Now this doesn't mean that Gyou'Un is faster or more skilled than Gai Mou or Ren Pa as a warrior, but it is just to point out that the hype around Gyou'Un doesn't revolve around the strength of his blows but his speed as well.
Gyou'Un's speed gets hyped again later against Ou Hou
Gyou'Un seems to be pretty intimately familiar with Ou Ki's glaive:
Notice that one of Gyou'Un's men remarks in shock that Shin's Glavie survived one of Gyou'Un's
"Glaive-Shattering Blows", the implication of this being that Gyou'Un typically shatters most glaives in one strike, which is absolutely bonkers hype when you consider that we have seen stronger soldiers (not even Generals, soldiers mind you) block blows from people like Tou and
even Mou Bu just recently.
Anyway, the implication of this scene here being that Gyou'Un has personally encountered Ou Ki before, which really wouldn't be shocking as we also know that Rin Ko himself broke through Ou Ki's defenses and landed a hit on Ou Ki at one point:
And Gyou'Un also explicitly states that he fought to claim the heads of all of the Qin Six Great Generals:
Which includes such powerful warriors as Ou Ki, Kyou, Ou Kotsu, (and really Shi Ba Saku and Haku Ki likely were very strong warriors themselves as well, not Ko Shou as it was explicitly stated that he had no fighting ability).
Speaking of slaying the Great Generals, let's talk about the Rai Goku:
This is a tactic
specifically created by Rin Shou Jou, to slay the Qin 6
And it is
explicitly stated that Gyou'Un has slayed Generals and Great Generals before using this technique. And keep in mind, other Great Generals could be people even as powerful as Man'U who we are currently seeing overpower Mou Bu. Man'U being a complete unknown to us but also attaining such a massive level of strength, it's not impossible that Gyou'Un slayed people of such caliber before.
In fact, Ou Hon only believes that he can slay Gyou'Un
specifically because he also slayed another Martial Great General in Shi Ei, who reached the rank of Fire Dragon by winning suicide-mission after suicide-mission and honed his spear in hellacious conditions
The point that I am trying to make with all this, is that
it is absolutely clear that Gyou'Un is one of the strongest warriors in the entire Manga despite never being made into a Great General himself. As we might expect of the man called
The Sword of Rin Shou Jou (referred to as Ren Pa's equal, and Gyou'Un was Rin Shou Jou's offense and his answer to the Martial Strength of other Great Generals.
Now, let's get back to Bananji for a second. Ren Pa was stated to be an equal to Bananji, and we actually did receive a direct comparison between Kaishibou and Gyou'Un:
When Bananji and Akou fought equally on multiple occasions,
but it was specifically highlighted by Hara that "even Gyou'Un by himself is....[Too much For Akou who is Bananji's equal as a warrior]" That last part was just added by me of course but this is the implication lol.
So let's wrap up this gargantuan tier post:
1. Gyou'Un factually has greater hype than Ren Pa as a warrior
2. Gyou'Un was explicitly and multiple times stated to have been Rin Shou Jou's Sword, and Rin Shou Jou was regarded as Ren Pa's overall equal
3. Gyou'Un has in fact slayed Great Generals in the past, and he also fought to slay the Qin 6 when Rin Shou Jou was alive
4. Ren Pa has been compared to Kaishibou and Bananji multiple times in this manga, and Hara went
out of his way to highlight Gyou'Un as being superior to Bananji.
I feel like I could go on if you can believe that but this will suffice for now lel.
