I love my rotor and have never had any problems with it. The only time it has ever jammed on me was when I was using really terrible paint and when I was playing woods and a small stick fell in the speed feed. If you're going to be playing tournaments then paint shouldn't be an issue, and as far as manual feeding with a dead battery goes you should always have fresh batteries in all your gear when you start a tournament. So, I would choose rotor, but that's just me.
EDIT: Also, I play in south Alabama so I know a thing or two about playing in high heat and humidity, and I still don't have any problems with my rotor.
