to be honest, not really. all top tier fuels are the same, just different brands add different detergents and additives. i know when shell added their "oxygenated" fuel, i lost about 2 MPG consistently, so i switched to 76. and when i ran chevron with techron, i noticed the car felt a little unresponsive. (this could all be in my head of course..)
