The two threesomes I've had (not with hot girls, 6s and 7s) were not remotely as exciting as porn had led me to believe it might be - although I'm sure that could happen given the right circumstances, but it's not something I'm chasing anymore. Multiple condom changes didn't help things along either.
I'd pick the one REALLY hot girl. I've never banged a genuine 9, let alone a 10. However I definitely wouldn't expect the sex to be any better - nor my arousal necessarily higher - than with a 6, 7 or 8.
