Which Role Should I Play?

So this is a big problem for me. I enjoy Mid Lane and Jungle very much. They both are able to assist people anywhere on the map, they seem to have the most depth, and they have a huge impact on the game. My best champion is a mid laner (Aurelion Sol), but the majority of champions I play are junglers. I'm trying to figure out if my best bet would be to play as a mid laner and get really good with Sol, or play jungle and get good with a few champions. (Basically, if I go mid I'm going to mostly play Sol about 80% of the time, with other champs when necessary. But if I go main jungle, I'll play Rumble, Gragas, Zac, and Kindred depending on which is needed. Mostly Rumble. I once tried Aurelion Jungle and it was the worst experience of my LoL life.)

Any help would be appreciated.

P.S. I didn't know where to post this, so I just posted it here as it would have a lot to do with my gameplay from here on out. [slayer-pantheon-thumbs]
