>>54>krav magayeah if you consider kicks to the balls and hair pulls and other pussy shit as decent self defense
For defense purposes kenpo or daito ryu aikijujutsu would be good, systema (the spetsnaz one) or sambo is bretty gud too. Did aikido before wish I did kenpo instead though. Boxing is always good in street fight situations. Really depends on what you want from martial arts, as becoming good in any martial art will give you good confidence.
