I say oden ngl, why? uhhhh roger.

Katakuri is the weakest 1st commander and Oden is admiral level.

Katakuri the weakest commander ? Luffy in G4 barely won against him, what's more Kat could have easily ended the fight early if it wasn't for Luffy running away from him.

Kata is weakest 1st com? He is the strongest. And you are overestimating Oden a bit there.
