I train BJJ so my opinion is a bit biased but BJJ is a necessity for mixed martial arts because unlike traditional martial arts it translates well into fighting without rules. Everyone wigs out about thier style but they miss the "mixed" part of MMA, know BJJ, learn some Judo for takedowns, the same for Greco-Roman. Do some straight boxing, Muau Thai, Kenpo or whatever. Do it all, just remember that the most useful, basic attacks that work, come from BJJ and Kickboxing.

Judoka

I won't be biased about Judo here and ill try to offer the best i can.

BJJ is very common and there is a reason why. Great submission game. Almost every single submission came from Judo(even the Omoplata) but BJJ has gone and become more advanced on the ground while Judo has become "less advanced" because of comp rules. The Judo ground game is still world class though, BJJ is better though but Judo can teach on the ground getting into dominant positions(A fine example is Minotauro Nogueira who uses Judo newaza with his BJJ). Although Judo's primary thing is throws etc although in ground work there are still some things that can catch BJJers off guard.

Unlike some have said here about throws is very untrue. Judo is easily adapted to MMA. I haven't trained in no gi Judo before and when no was doing no gi wrestling i pulled off quite a few Judo throws. You just have to see how to adapt what replaces this movement etc. Also unlike others have said Judo has been used successfully by many in MMA it's just people don't know it, big throws are a part of Judo but there is A LOT more.

Karo Parisyan has a no gi Judo book coming out with something like 35 throws in it.

They are both good, The only one who decide here is you. We don't know you. Although if it is possible choose both, That would be the best option after all like the guy above me said it is "mixed" martial arts.

Wtf? Half the submissions in Judo are armbars so that blows that call right out of the water straight away.
