I'll add to what has already been said about GURPS Martial Arts that the GURPS Martial Arts book has options and gives advice for different styles of play depending upon how gritty & real you want things to be or how over-the-top & Crouching Tiger Hidden Dragon you want things to be.
If you wanted to mix even more supers elements into your game, there's also GURPS Powers and GURPS Supers. Everything in GURPS is built using the same rules and same mechanics. It's possible to mix and match pretty much anything.
Like Hero, GURPS requires some number wrangling, but most of the math you do in GURPS is front loaded and done during character creation; not much is done during actual play. From what I remember of Hero, less is done up front, but there's a bit more math involved during play.
If you're unfamiliar with the system, GURPS Lite is free, and it gives you a pretty good idea about how the core mechanics of GURPS work.
