Wing Chun is good, I would give it one stipulation. There are a couple different kinds of instructors. Some will teach you fighting with it more right away, will perhaps even start teaching wooden dummy within a few years, and will put practical application first. Others will have you doing chi sao for years before you get much fighting out of it.
My suggestion - find an instructor who will do it all and hit the technicals but emphasizes the fighting aspects first. Another thing - if you can find an instructor who teaches both Wing Chun and Kali (particularly Inosanto style of both) or Wing Chun and Silat, these styles tend to interact positively and mutually reinforce each other. Very traditionalist Wing Chun can get ritualized and over-drilled where the fighting loses emphasis or particularly where everyone keeps a straight line while fighting and never breaks line or tries to pass; when its like that you tend to get less out of it because you're limiting real life options and enhancements to your Wing Chun for historical purity.
That said, like I'd suggest with any art - do your research, observe as many instructors as you can and try go get a sense of who moves the best as well as who's students also seem to move well.
