I found this post on Sherdog and I agree completely:
"Krav Maga brown belt.
Want to know how I got into JiuJitsu?
A guy came in to the gym and during sparring sessions was just ripping everyone apart. People called it really cheap, but I was fascinated. Throw a punch and he ducks under for a trip into mount. Bear hug him and he tumbles for a leg and hits you with a foot lock/knee bar. I thought he was a black belt in jiujitsu because of how hard it was to deal with him once things got on the ground.
When I found out he was a blue belt, I wanted to learn more of that system.
I really think Krav is a great system if you're already good at something else, or you're practicing against people who like to play rough. But lots of people didn't want bruises, scratches, or sprains... so we could never really drill at high speed.
Also after doing both, I'd say the ground defenses are really inadequate. It's about how to get up and get to fighting, but do you know how hard it is to get even a 4-stripe white belt off of you if you're only training ground defense 2 hours a week?
You cover a lot of defense against 1 or 2 handed chokes from mount, head locks from the side, and 2 handed chokes from the rear... slight problem.... how many BJJ people have you ever seen use a 2 handed choke or head lock? And even as a blue belt, I still can't get out of some triangles and arm bars. So how are you going to learn that in Krav 1-2 hours a week?
My only problem with Krav is that everything they do, someone else does better.
Striking? Boxers do it better, and they don't ever get hit full speed, so good luck taking a punch
Kicks? Karatekas, soccer players, and TKD do it much better
Ground work ? Bjj guys do it a lot better
Wrestling? Non-existent so any martial artist person does it better.
So if it ever came down to it, where exactly would a Krav guy take someone where they hope to have an overwhelming advantage?
I know Krav pretty well, and BJJ at a very very average level. One on one if things hit the fan I'd rather fall back on BJJ. I'm not outstriking or out kicking anyone...
I've seen guys come on and just out punch everyone because of their size and toughness from day 1. And I've seen what I can do to new guys, even wrestlers, on their first day of BJJ. But that doesn't mean I'm above doing an eye gouge and nut grab from back mount. It's my new over-under control
