jg or top lane Ranked

JG

Toplane sucks, the only thing productive to do up there is play a tank. JG can at least impact the game and influence laning phase (read: gank bot).

It really boils down to what you're best at. Jungle requires macro play, not much micro. There's a ton of decision making that most laners don't appreciate that goes into good jungling. Top lane is mostly mechanics, being able to poke, zone, farm, trade, and not die. It's really a 1v1 show of skill against your opponent to see who can snowball.

If you're good at both or willing to learn, I'd say jungle, though. You have more control over more lanes, and can choose which lanes to try and snowball. In top lane, there's a chance your team will lose even if you win, and there isn't too much you can do about it.
