If you can set aside the amount of bad matchups, Bane is a char i'm beginning to use more than my original main (DD). Sure his combos aren't as intricate or lengthy as Batman or Grundy, but his Venom is such a unique system you'll begin to really engage yourself in the game as opposed to just "knowing" what to do in certain situations. The inclusion of 3 Levels of Venom begs the player capitalize on situations, or pay the price of getting zoned out.
Of course, this is really a matter of gaming experience, so you gotta ask yourself what it is you want out of the game. To win or have fun?
Second I'd recommend Ares. If you don't mind zoning, training your opponent, playing keep-away, then pick em. Seen some smart dudes play em and I use him as well.
