What is better for self defence; Jow Gar Kung Fu, Wing Chun, Shotokan Karate (JKA) or ITF Taekwondo?

Well Taekwondo is sadly ineffective in a street fight. I practiced tkd for 5 years and its fatal flaw is that its pretty much useless in close quarters and a good 90% of people just bullrush you in a fight. Ive never done the other two disciplines so i dont know about those.
