Since you said please.
Ace is too fast for the slowest M3 member Zoro, Zoro's CoO is also the weakest amongst the M3, he got outmanuevered by Carrot, who got blitzed by Daifuku. He also got hit by Hawkins's nails. He hit Kuma before pre-Ts however even pre-Ts Sanji and then Ivankov blitzed Kuma so its nothing but PIS. We know Zoro is even slower than run point Chopper in a race as Oda said in SBS.
The only reason Teach hit Ace is because of darkness gravitition pull.
He moved faster than even Admirals.
Ace, who is fast enough to counter Aokiji's sneak attack from behind; (when Ace was already wounded due to Teach).
--- Chapter 572
And he moved faster than Akainu;
--- Chapter 573
Ace is so fast that he creates a fire tunnel before the explosion from the cannon balls hits him and before hits Luffy.
--- Chapter 571
Ace is faster than Zoro.
Durability\Stamina; Ace is better as well, he fought Jinbe for 5 days and then he took an attack from WB and still didn't lose consciousness while Zoro loses consciousness after getting hit by nerfed Killer Kamazou.
Fire power: The only reason this is high diff is because Zoro learned cut fire, that doesn't mean he won't get hit because Ace is faster. Ace has other attacks like hotarubi hidaruma which can't be cut by Zoro. Ace showed island level destruction which is also bigger than anything that Zoro cut. Either way Zoro will get hit by superior fighter such as Ace. He even got hit by Hawkins's nails and Carrot's electro.
While Ace managed to
hurt even Whitebeard with his attacks and he stopped Aokiji's attack.
As for bounties 550 > 320. Zoro has a long way to surpass Ace.
Kaido literally tanking everything they throw at him on purpose, Lolo even missed big ass dragon Kaido despite getting help from Law's teleportation and distraction advantages from Luffy, Killer, Kid and Law in a team battle. Lolo is too slow.
