I think it's hard to say which martial art anyone would like. I've heard of people cross-training in other arts including judo, iaido, jujutsu, karate, wing chun, capoeira, and others.
I'd say go to a few schools and see if you like what they offer. Try them out, if you get the chance. Many schools will let you take a class for free or will have cheap "introductory" courses.
One warning -- don't get your plate too full...
