Depends on what youre looking for. With the bilsteins at the 2.5 notch youre going to get a stiffer ride and less travel of the suspension than getting the bilsteins at no lift and using the spring purely for the lift. If its all highway its less of an issue than with off roading
Id also be careful about "leveling" the vehicle. If you put any weight in the rear end, it will sag and youll be high in the front. I prefer to keep a slight rake of at least an inch
