I say Judo, since I am a Judoka. In my dojo, believe it or not, we train for the ground, and stand up equally. My sensei, Kevin Doherty, is a two time olympian, and he was also a world champion, so he is super strict, and he always lets us train hard on the ground because he said these days, a lot of Judokas get lost as soon as they go to the ground during a match. It all depends on wether u like stand up grappling, or ground grappling, but as a lot of BJJ guys will tell u Judo gives u bad habbits on the ground, and it has a lot of flaws, is not true, and lets say if it was, well BJJ gives u bad habbits with stand up grappling, and that is true. But just so u get it straight, most Judo schools focus more on stand up grappling, and most Bjj schools focus on the ground. And one more thing, I think Judo focuses more on ground grappling, then Bjj focuses on stand up grappling, right? Correct me if im wrong
