For what purpose? For what chambering? 15X or 25x is a lot of magnification(too much really) if your hunting deer with a .308. Not so much for very long range target shooting or varmint hunting with a .243.
Most shooters put a variable on one magnification and leave it there. There really isn't enough time to fiddle with magnification when hunting other beasts.
