Golden Freeza vs SSJB Vegeta
Was pretty heavily implied Freeza buffed up since their first meeting. Vegeta saw him fight at the ToP, and seemed stressed thinking about him at the Broly movie.
Freeza himself spoke of the two in tandem as the obstacle. Not, that he couldn't beat one of them.
And to be fair, Goku and Vegeta swapped in and out, without offering him nary a senzu.
Who wins?
