is jiu jitsu the best?

I feel that jiu jitsu is the most dominate marital art, am I correct? And is a knockout an accidental win?

I think Muay Thai is a close second, and a KO is not accidental on a counter strike but if your just putting a beating on them to wear them out like Nick Diaz dose then they get KO'd along the way then yes.

i think the best is some kind of blend of wrestling and jiujitsu. or striking and jiujitsu. actually i think anyone who is able to blend two or more of those three disciplines makes for an elite fighter.

anderson silva - muay thai / bjj
edgar - wrestling / boxing
gsp - wrestling / striking / bjj
jones - wrestling / striking

but now that i think about it the heavyweight division has always been loaded up with a lot of one-dimensional fighters but guys like vasquez, jds who mix a couple of disciplines are starting to come to the forefront.

fighters today know all the good shit from each martial art i was just thinking about specialist fighters, witch has more?

depends on the person. Personally, I think the training that goes with wrestling combined with bjj is the best for grappling.

I'd be curious to know to what extent striking or wrestling-based fighters practice jiu-jitsu for MMA. I figure everyone learns how to create space and get back to their feet from the bottom; defend/execute pop-triangles and armbars from the closed guard; defend against/avoid guillotines; and throw in some RNCs and, if you're a wrestler, some head-and-arm chokes, and that's the world of jiu-jitsu for the non-jiu-jitsu-based fighter in a nutshell. That still leaves guard passing, guard recovery, sweeps, which IMO are woefully underdeveloped in MMA.
