they're going to be very close to the same thing since they'll be stock struts that are shaved to accommodate sleeves being pressed onto them for the spring seats to move up/down on. so....whichever is cheaper since you clearly don't care how the car handles.
but to also throw another wrench in your plan anytime you change the ride height you completely ruin the alignment so your idea of raising it at the track while you're there, if that's what you meant, will be a bit risky considering the car will be all sorts of wonky after the ride height changes significantly.
