There's a massive difference between jkd and wing chun nowadays. If you're looking for a jkd class and can't find one, then a wing chun class will take you down an entirely different route.
It's not really what art you attend, as long as the students are punching and kicking each other, as well as groundfighting, then you can't really go wrong. Wing chun won't teach you how to fight on the ground.
