KnightSaga
Loved both in my youth but have like them less as I got older. Maximum Carnage seems downright silly by today's standards (went on too long, campy dialouge, action over plot or character development), while at least the 1st third of the KnightSaga was superb give or take a hiccup here 'n' there. Then again Maximum did spawn a killer beat-em-up, and of course its always great seeing any Spidey-Venom-Carnage throwdown.

But this time I want to vote Bane, so, KnightSaga.
