It makes sense for me and tbh its more comfortable than the PS3 controller, especially the damn trigger vs the PS3's horrible L/R2 which gives me muscle cramp if I play burnout or motorstorm for too long.
Then again, this type of things usually only ever get me when I'm doing QTE and I don't have many 360 games that have hard QTE so it could just be the situation.
But in term of controller comfort 360 > PS3.
