hea im jon well a year ago i was stuck in the same position but with all martial arts and i found that it depends on what you want to learn! like with ju jitsu its more of ground fighting and grappeling! and judo is more like karate and other standing fighting! so really its what you want to learn!
if you want to fight mostly on the ground and do holds and stouf then do ju jitusu. and if you want to stand then do judo! the decision is yours. i hope i helped at all!
