I have both, the gen2 is better in most ways than gen1, better glass( much more clear and better contrast, all the way to 30x), better turrets, better zero stop. In all, gen1 is a very nice scope, good glass to about 25x or so. clicks are repeatable. If you can not hit with gen1 xrs, a gen2 will not help you hit a target any better. But is sure nice to have nicer glass on the gen2.
