Namor, domino, colossus or other mutant?

If I could r5 one of them, which would it be? I dont have 5* namor but still, it's best to know. P.s. neither are duped

It's between colossus and domino. Omega is another level if you have him and if he's max Sig and if you run suicides. I'd say colossus because he has the immunities, utility and also crazy damage not as good as dominos but still
