Best hair removal: shaving, or pulling the roots out?

[Hi :)]

I've been shaving for over a year now, (I'm 14 by the way), and I hate it because the smoothness lasts only a day and I get stubble really quick. Also, it gives me a lot of annoying side effects, like really itchy skin. My mom suggested that I use the shaver she uses, which actually pulls out the roots of the leg hair instead of just cutting it at skin level. She says it will last longer. If you have any experience, could you help me? Will the "pulling roots out" thing make my hair thicker and darker or something? Any side effects? Thanks.
