Practicality is important to me, and difficult to judge without some experience. Properly practiced Jujitsu, Sambo and Krav Maga are practical. There are useful lessons in Muay Thai and hard American kickboxing. Judo is acceptable, particularly if you are not possessed of great strength. Wing Chun's pitch sounds reasonable, but I cannot speak to its efficacy.
Avoid most schools of Karate (Kenpo especially), Capoeira, Aikido, Tae Kwan Do, and most of Kung Fu.
In any case, there are bad instructors to be found for every art. Caution is in order.
