Sorry, Gintama messed up my memories about historical person. LOL.

In actual lore itself, Gensai is noted as worthy opponent for Shinsengumi which consists of notable swordsman. Its said Shinsengumi consider other Battosai as 'serial killer' but Gensai as he's the only Battosai, among those four, who capable to deal with Shinsengumi head-to-head.

I put him above Okita because Gensai once deal with Saito, which among three strongest member of Shinsengumi (Okita is also among those three). Considering her "Weak Constitution" as well, Gensai clearly above her--if not because Saberface and discrimination toward male. LOL.

With Okita skill is said as 'destruct material' while Kojiro went close to 'True Magic', I do wonder what Type-Moon will gave to him as he's said to be the fastest. They already made Okada Izo, I expect other Battosai will be made as well.
