Most practical martial art?

I've never practiced Krav Maga but from what I've read and been told of it sounds very, very similar to (if not the same as) the military combatives I've been taught, which are really the only way go when someone's trying to fuck you up. Scooping out eyeballs and rupturing testicles, wonderful stuff. If you're looking to get into a barfight to teach some fucker a lesson for lookin' funny at your girl then good old fashioned boxing will work fine since you probably don't have to worry about drunken flashy kicks or takedowns (unless you're in japan?). I practice shotokan karate, it's not optimized like Krav Maga for use on the battlefield but it's well-balanced, and if you're good enough in anything you don't need to worry about getting beat up since most people can't fight for shit anyway.

Jam it back in, in the dark.
