Best style for street fighting?

if ur gonna learn something learn kickboxing.... they teach u how to use ur hands and feet properly... youll be able to ko who ever your opponent is with one kick.... BEFORE they even get close to you...... i was thinking about muay thai but for that theres alot of grappling involved and if you take that you will mess up your knees and elbows when doing ground work with the grappling... kickboxing you can knock any1 out before they even get close to u with just 1 good kick to the head
