lots of historical differances that Im sure you can find pretty easy using wiki or google! Main difference I know of though is the amount of guys Ive met who come from traditional japanese Jiu Jitsu backgrounds and are highly graded, even black belts - when they train with BJJ guys who are even good white belts, the BJJ guys will be all over them on the ground. No comparison. Ive not trained 'JJJ' so cant give credit to its strengths, maybe someone with experience can. 'BJJ' however is by far more dominent on the ground. That to me is the main difference!
