You've got that backwards. You want the rail to be grippy if you want greater spinning.

The other side says that to get the largest velocity the frisbee should grip the track without slipping so that the frisbee exits as the same velocity as the wheel is rotating.

That's backwards too. If the frisbee grips the track without slipping, your exit speed will be limited to half the tangential speed of the wheel, but you'll get the greatest spin.
