I need some opinions. I just ran another dedicated 15 amp line for my theatre... using 3 wire, 12 gauge romex.

I have a friend that says I should use 14 gauge instead of 12 gauge? I don't grasp that idea so can anyone please explain it to me?

Why is the thicker 12 gauge not good for the 15amp? As far as I know, it should be fine but I need peace of mind
