Should I get metal or ceramic braces?

I want ceramic braces and they're the same cost as the metal ones, the only problem is that people say the ligaments stain sometimes? I don't smoke or drink coffee and brush my teeth pretty often, so if I got them would I have to stay away from certain foods? I only drink water and milk and somtimes orange juice, so I don't drink anything dark. Also, I've heard they're more comfortable than metal braces. Is that true? Thank you!
