I get most of my Superhero fix from DC, but when I do venture in to indie Superhero books (Firebreather, Faith etc) I usually look for characters that are unique hand don't have a direct parallel in at Marvel and DC. Nothing annoys me more then a character that is just a knock off. Superman knock offs are the biggest offender. It's almost like creators don't want to be bothered coming up with an interesting power set (which in my opinion is the fun part) and instead just give their hero the standard power set.
