Hey! I am going to buy a new guitar, and im wondering if I should go for the Schecter Blackjack ATX C-1 or the Schecter Blackjack SLS C-1. The only difference is the neck. The SLS is thinner. Im only 15 so my hands are not really that big. So what do you guys think thin vs thick(er) neck?
Nobody can answer this question for you. You need to play both and see what you like more.

I wish I had a guitar like that when I was 15. Even though I generally don't like Schecters that much.

Some people are very sensitive to neck dimensions, some- myself included- aren't. It's a matter of comfort & preferences that (as pointed out) only you can decide.

Log off and play yer guitar!

Strap on, tune up, rock out!
Have you tried either? If you haven't try and track either one down and see what you like. Heck, neither the thick or thinner neck from Schecter may feel comfortable to you. It's one of those things where it should feel right.
