Just to give a bit of perspective, here are some of my thoughts on Queen for those that might be a bit disappointed with him:
With regards to Queen, to summarize in my own way, I think there are 3 main reasons why he might feel bit underwhelming to some.
- How his bounty compares to King.
The fact that their bounties are close gives off the impression that they are close strength wise but King's combat showings have been a lot more impressive than Queen hence why Queen looks underwhelming. But the first reason for this is that Sanji atm particularly with his current buffs is an awful matchup for Queen. Outta of all the high tiers atm, Sanji has some of the best base stats. Any commander that doesn't have either some sorta hax or durability is gonna get wrecked by him. Only 2nd Commander that I feel would put up a balanced fight against him is Jozu. On the other hand, in the same vein that Sanji is an awful matchup for Queen, King is an awful matchup for Zoro. So the matchup itself and the sheer martial strength of Queen and Zoro's opponents in comparison to them is the reason why they are being overwhelmed the way they are.
- Expectation vs Reality.
There is an implicit assumption that King and Queen are the same type of fighters, so we are holding both to the same standard which is one of the main causes of our disappointment with Queen.
King is full blooded combatant that has even be dubbed a "killing machine". This is someone that seems to have absorbed tons of martial arts and uses his own hybrid style where as Queen on the other is a bloody strong "scientist". Queen's threat comes from his "science" not his "martial skills". You'd see that most of the criticism that people haul at Queen is qualms about his martial skills. For instance, "he's too slow!", "all he can do is shoot lasers etc!". But keep in mind here again that matchup is very important. Right now, Sanji is as bloody strong martial artist that is also a speedster. To put tings into perspective, even the lasers these critics are looking down on with Queen are even more impressive than the catapult lazer ting King does with his head as Queen can use rapid fire with his lazer attacks hence making them a lot harder to evade. King's attack might hit someone like Zoro who is more of a tank type but it won't even hit Sanji's shadow. Not sleeping on Zoro's speed here as he's not really a slow character but Sanji is a lot more mobile than he is.
- Lack of lethality from Queen as opposed to King
As impressive and versatile as Queen's attacks are, none of them save his Bracoil Hold were lethal to Sanji and even that was countered by Sanji's exoskeleton awaekning. Whereas most of King's attacks have been lethal to Zoro. Again it is important to note that Sanji is currently the most durable character in the alliance atm, so Queen is effectively fighting a pseudo Dino of sorts hence why the damage Sanji has taken from those attacks have been minimal. So physical attacks for the most part aren't gonna have as much of an effect on Sanji as they'd have on Zoro for instance.
And this lack of lethality is what really sets people like Donflamingo, Katakuri, King etc. apart from Queen
All that said, there is really nothing we can do about the first two aforementioned points, it is what It is, people just have to try to be a little more objective. I was bit irritated myself but after giving it some thought I've come to terms with it. That said, something can still be done about the final "lethality" point if Oda allows Queen to use his plagues the way we know he can. As even if physical attacks might not work on Sanji, biowarfare certainly should. And on this point, Queen is even more lethal than any of the other Yonko Commanders imo. This is one of the perks of Sanji fighting a mad scientist as opposed to a true and true martial artist.
