I have a number of supers rpg's. I have issues with all of them, though. I wish there was a game that combined all my favorite parts of each into one amazing whole.
Champions/Hero is too complex and it requires minis and hex maps. It does have really good supplements, easily the best in the genre. I'm torn on power creation. I can make just about any power, but I end up with a long list of stuff just for something simple like an energy beam that ignores armor and can kill.
ICONS doesn't let the GM roll dice. It's a pretty good system, otherwise. But I like dice, and I'll be the GM, so it's a no-go. I also prefer points-buy as the standard form of character creation.
Mutants & Masterminds 3e/DC is also too complex, especially during character creation. It has many of the same issues that Hero does. Freedom City is a fantastic setting book, too bad it's not planned for the M&M3 rules.
Supers! is the best supers game that I've found, but it's actually too simple. I almost want to type the whole thing into word, and then write an extra 10 to 20 pages of powers and rules.
Savage Worlds Supers Companion is kind of cool, but I'm burned out on SW. I also would like it more if it was a single book, instead of a supplement for the rules book.
Villains and Vigilantes is too old school for it's own good. Your character is you, but with supers? And you're supposed to judge your friends stats? Yeah, right.
BASH! Ultimate has a decent system, but the writing puts me to sleep. Not sure why, but it is the most boring rpg ever written, to me.
