Who is the better mutant in today’s meta

GNASTY

It’s 2020. The grandmaster is defeated. Act 7 is in Beta. Who is the better mutant between these three champs with utility and general usefulness for exploring story mode end game content in consideration?

TP33

Iceman is good but not yet a 6* (but coming soon!) but even then collosus has better damage

Emma is alright defensively but not enough damage for what she does

Collosus is an act 6 beast and he clears through 90% of the game within a sp2
