Fit Buu power increase

[Natasha Romanoff]

Do you think this increase could have been from Regular Fat Buu to Fit Buu rather than Good Buu as this is the form Goku has experience fighting against?

Should be Good Buu imo.

Though recently, some people think Good Buu(after splitting up) and Good Buu(Vs Kid Buu) are different Buus.

I heard the Japanese call him Slim Buu but Fit Buu just fits so much better lol.

Fit Buu rings-out base Goku so it's fair to say he became somewhat stronger than base Goku. It's a ludicrous leap in power in the anime.
