The best version of Carol was Binary. Hands down. No contest.
And this coming from someone who loved her in the (original) Avengers comic and collected her Ms. Marvel run (the original) back when it came out.
I just thought Binary was such a great up in power and appearance for her.

And I enjoyed Genis-Vell (because his series had Adam-X, check mark!) but also because of the development he got in Avengers Forever then in Thunderbolts.

Right up to his demise. -sigh-
