Everyone has their reason for choosing their style, it could be because of something you saw as a kid, a family member, movies, a fight you witnessed and saw the victor doing things that amazed you, etc. I chose BJJ because it works, the groundwork, the culture once I started rollin is amazing. I haven't experienced the "we are better" vibe in the schools I've been to. There is a confidence among BJJ guys that seem to be prevalent in styles that actively spar (boxing, MT, Judo, etc). I am looking at other styles though, BJJ is more expensive than many other arts. What about you?
