I wouldn't get an XTR when I could get pretty much the same thing with a TAC30 or MTAC, for hundreds less. I actually like the reticle on those two better than the XTR. The XTR reticle is a bad copy of the ACOG horseshoe. It has the BDC, but the stadia lines are not the right length to range as you do with the ACOG.
I don't have any experience with the Leupold.
