There's thousands of them. What ones do you know, which ones do you swear by? Me, I used to use taekwondo exclusively, but then I learned boxing. Now my dominant style is good old fashioned Sweet Science. Ones I know well enough to teach: 1) Boxing (default style) 2) Taekwondo 3) Hapkido 4) Foil fencing 5) Epee fencing 6) Sabre fencing 7) American kickboxing Ones I've tried: 1) Submission grappling 2) Karate Ones I picked up a few moves in, don't know with any serious expertise: 1) Kendo 2) Iaido 3) Escrima I would really, really, really like to learn cold are Silat and Escrima. If I get those two, I think I'd be done learning martial arts. I always wanted to dual wield properly. Also, goloks/guloks, rattan, etc. are juuuust big enough to be sabre-sized. Weapons like that I can always use ok.
