I'm torn between hair stylists. Should I see my old one or my new one?

Several weeks ago, I called my salon to schedule a haircut. My stylist wasn't available, and another stylist was recommended to me. The new stylist did a great job cutting my hair, better than my old stylist. Now I'm torn. I'm ready for my next haircut, but I don't know who to see. Should I see my old stylist, or should I see my new stylist? And why?
