If you're leaning towards singing then I think you should sing. Rappers usually have a lot of bass in their voice but there's no rules really. Wiz khalifa has a very high pitched voice and he raps.
Whichever you decide to work on you'll be great at. Just put your hours in. It's a grind for real

Oh, and don't use autotune please. I mean... If you're going to practice to be good at something... Don't rely on a crutch to get you there.
Marathon runners don't jump in a car in the middle of their practice races. They run the whole way.
You must reach deep into your heart and decide if music is what you want to do for a living. And if it is, you have to keep the mentality that YOU ARE THE INSTRUMENT. A living breathing instrument and you require no crutch
