Doffy can only best him badly when he's not in G4. in the end, Doffy>=Luffy which is the only version of Luffy near the Top Tier.
The only reason he caught was because he was off guard, you don't need to bust out to be superior, while the attack used against DD wasn't stronger and even if it was (which it isn't) Jozu himself was caught off guard, being on guard makes a huge difference.
That isn't a solid counter argument, it's not clear if it was either a shading or a bruise and it's gone the next time we see him.
Only time Luffy physically pushed back Fujitora was in the first initial blow when he wasn't on guard hence the exclamation point. Don't use COO is an excuse when it has been wildly inconsistent, the use of the exclamation point makes it obvious that Fujitora himself was caught off guard by it.
Who??
He's not stalemating Kuzan or Mihawk off screen like Jozu and Vsita nor is he clashing with Kziaru in the same manner Marco did ot stop Akainu's advance like Marco did either.
