Well that would probably depend in large part on the quality of the schools in question. I'd say JJJ gives you more options (strikes, takedowns, some grappling/submission work). But if the JJJ school is just based on repeating techniques and doing kata, with no interactive drills and sparring/randori, then I'm not sure its going to do you a lot of good. But I'm a big proponent of training against real people. If the JJJ school doesn't have that, and the TKD people do (e.g. sport TKD), then I'll take the perhaps unpopular position and say you're better off working your kicks against people who are trying to kick you than going through static kata everyday. But check out the schools, and then go wherever you feel most comfortable. You're not locked into one art forever, so as long as you keep an open mind, you can always cross-train when the opportunity comes along.
