The krypton one is super cool

The supergirl one looks like a guy with green paint and a blond wig

3rd suit is good but ruined by the bad makeup and hair.

Krypton braniac wins unequivocally. That design is the best live action adaptation of braniac that we have gotten yet.

And why is braniac 5 here? He's a different character.

Because otherwise there would be no other Brainiac suits for a poll. Also I think it's fun how they used the Smallville Supergirl actress for Brainiac 8.

Cw gave a role to many past DC actors, it was fun seeing them in a different role.
