Depends really on what type of character your fav is.
if its a gag character whos only purpose is to be comedic relief in the story (Buggy, Usopp, etc…) then his strength doesn’t matter.
if its an actual serious character who is relevant to the plot (Yonkos, Admirals, etc…), then his strength ABSOLUTELY matters, otherwise nobody will take him seriously in the story.
Imagine if Teach was Chopper level? Do you think any of the plans he schemed that made him so great and beloved as a character would work then?
He’d just be all bark no bite and get his ass handed to him every single arc
Noone of the fanbase will ever take him seriously.
