Cosmo's best feat is invading Adam Warlock's mind, and hurting the Annihilators with his TP:

Grodd's feats mainly involve the Flash, of course, but he has other feats as well against people like Superman.
In any case, I give it to Grodd, due to speed. In a quick draw contest, the guy who is able to mindrape speedsters has a decide advantage.
Being more of a dog person, i was holding out hope for Cosmo, but your argument's nutshell is what i was thinking, too.
