Zoro's top tier feats: Getting out of Fujitora's Gravity....and Clashing with Fujitora twice. Clashing with Fujitora in Dressrosa is not a feat multiple individuals did it... So the only feat here is Zoro getting out of the Gravity. That is Zoro's top tier feat..............
Now lets compare that to what Jimbei has done:
Jimbei being conscious from Akainu's attack. When we saw it has the power to Kill an individual instantly.
Jimbei Blocking A Yonko's Blade with his His arms coated Armament Haki not even using a weapon to block.
Saving Luffy's Ass from 1st Commander.
Defeating a Warlord: Moria is stronger than anybody Zoro has defeated in One Piece.
As you can see what they've done is not comparable. No matter how strong you want to make Fujitora.
