Who do you find yourself controlling most of the time? At first I played Serah because she's the main character and her roles (RAV, MED, SAB) were ones that required a bit more user input than Noel's. But then Noel grew on me and I feel like he's more of a lead than she is. Serah's pretty annoying most of the time and I don't feel like she adds anything to the game. Noel however has a pretty strong personality and his characterization and voice acting is very good.
