Wow, that video is nothing short of hilarious.
Seriously, JK, try out a class and see for yourself- (it's funny, I think we're all saying the same thing here...
My 2cents: KM focuses on getting home safe- not engaging or 'squaring up' on your opponent, but reality-based training for the purpose of self-defense. Kravists arenít preparing to go 5 rounds or do a single-elimation tourney (although, Iíve seen some that have the cardio and heavy hands to do so). But given a situation, theyíre going to fight like MF to get themselves out of the situation. That includes, possibly running for help, if necessary.
And although sparring is not an everyday thing (at least not in my school), there are some KM schools that have sparring in their 'FIGHT classes' like mine, which include (but are not limited to) fighting instruction, fight drills and sparring where they spar much like kickboxing sparring- with gloves and head/shin gear. Other schools have grappling workshops.
As PSYOPS stated: It all comes down to the individual. And to repeat what Dedicated1 said, whatever MA you train in and enjoy- that is the best one. I love what I trained in- BJJ has great techniques and I can't get enough of grappling and the feeling that comes from competition. Thaiboxing is great too. Their camps are designed for different goals. KM is a welcome addition to my repertoire. The difference between all three is that KM is an open system; it can transition all your skill sets and attributes from the other two into its system.
