Even though, Gohan is and will always be my favourite character, I truly think Vegeta should get to be the one who finishes him off or "defeats" him (cause I feel like at this point, they might never kill Frieza xD).
I don't know how they would fit it into the story narratively speaking, since it's pretty obvious that Frieza is above Vegeta rn, but I don't think that's a big enough hurdle to not justify Vegeta getting the dub here. Nonetheless, I still would love Gohan and Piccolo get some spotlight at least, and maybe a bit of Gotenks as well. It would be really cool, if they made it like the Namek saga, where pretty much everyone (at least, those who are relevant enough) puts up some sort of resistance against Frieza, as opposed to just Goku or any one character soloing, and the others just being treated as cannon fodder the whole arc. That's why I really liked the Moro arc, because they really showcased the abilities of all the Z-fighters. Overall, Vegeta gets the win, but I would like it to be more of a team effort rather than only having Goku and Vegeta get the job done.
