You say powerscalers don't understand One Piece, but then make a thread about powerlevels. That doesn't make any sense.
From a narrative point of view if you ignore the "powerlevel".
Chapter 5: "The Pirate King & The Master Swordsman". Only crewmate Luffy actually sought out for strength.
Arlong park: Arlong is scared of Zoro's potential because of his face when facing death
Loguetown: Smoker is reminded of the PK when seeing Luffy's face when facing death. Luffy's luck is tested when a lightening bolt comes down with the sword only inches away from his neck. Zoro's luck is tested when he swing the sword up and it just goes around his arm instead of cutting it off clean. Just coincidence guys!!!!!
Post-Arlong: Wait a minute, the guy who luffy said he's surpass in chapter 1 & the guy who Zoro said he's surpass in Baratie... were rivals?
Whiskey Peak: Both Tie
Water 7: Both get put into similar situations that gain similar reactions with the wall stuck & chimney
Ennis Lobby: Zoro being mistakened as the Captain
Ennis Lobby fights: Zoro beats Lucci's inferior Kaku in a mid-diff fight. Luffy vs Lucci goes to a point where Luffy doesn't even win without Franky's interference at the start, and even then went to the point Luffy can't stand up. That shits on the entire "doriki" point of view.
Thriller Bark: Zoro gets his willpower tested by Kuma (Dragon's underling) with enduring all of Luffy's pain, where he's got only a tiny chance of making it out alive.
Saboady: Oh dang Zoro was going to cut up a Celestial Dragon if Bonney didn't step in. Oh dang Luffy punched a Celestial Dragon because nobody came to stop him like Bonney. Pure coincidence. Oh my Zoro isn't treated as your typical right hand man like Killer & Bepo, but instead it's Sanji.
Impel Down: Luffy gets his willpower tested where he's only got a very small chance in making it out alive by another one of Dragon's subordinates, Ivankov.
Timeskip: Whoa both of their training involves directly with learning of Haki. Where they're fighting superior opponent(s) while doing it.
FMI: Whoa Luffy faced off against Zoro's final opponent, and Zoro faced off against Luffy's final opponent before the final fights?
Post-FMI: Is that Zoro challenging Luffy to a competition?
Dressrosa: Is that Zoro saying Luffy should've told him about the tournament, where he would've had to compete against Luffy? Is that Luffy & Zoro who go up against the admiral in the arc at different moments of time?
Start of Wano: Oh Luffy & Zoro having side by side speed moment, sick. Both get their "duo time" before pairing up with the entire squad again.
Wano end of Act 2: Oh wow do my eyes deceive me, it's Zoro & Luffy training near each other related to Haki mastery.. where if they master it, they'd be able to damage Kaido. NO! It certainly can't be!!!
Rooftop of Wano Act 3: Luffy & Zoro doing teamwork in their rooftop fight. Zoro landing the biggest blow on Kaido in that 5 vs 2?! Zoro taking on the biggest attack from the emperors in that 5 vs 2?! It certainly can't be!
Post-Rooftop of Wano act 3: Zoro faces an opponent who's even harder to damage than Kaido?! And despite his condition he manages to cut him up after he gains the power to do it?! Wait a minute, I wonder what would've happened if Zoro got the "reset" against Kaido like Luffy did multiple times, where now he's able to 1 shot somebody who has much more harder to damage than Kaido, when the only reason he struggled against Kaido was because he couldn't damage him properly. I wonder what would happen now.
End of Wano act 3: IT CAN'T BE!!.. Zoro & Luffy are out together side by side for the same amount of time?! Oh no this doesn't mean anything at all.
You can't talk about narrative and powerscaler non-sense, and then make a claim like Luffy >>>> Zoro, which goes against the very narrative Oda has continued to establish since start of the series. That The Pirate King & The Master Swordsman will always be near each other.
Portrayal / narrative is the last thing you want to use if you want to claim Luffy >>> Zoro, stick to "feats only" for that.
