I have an SHV F1 on my AR10 in 308. It is good to 800 with ease. At 1000 it lags a bit in clarity and at the 1250 on the range I shoot at it takes some added concentration to really distinguish edges. I had my NXS 5.5-22x56 on my 260 bolt rifle and it was a bit better. I now have an AMG 6-24 on that 260 and the clarity at 1000+ is a noticeable improvement. I maintain the SHV on the AR10, though.
For the price points you noted, the XTRIIs are quite functional. I sold my 5-25 XTRII in favor of the SHV F1 as my personal preference was for the MOAR reticle over the SCR. That was a personal compromise on my part as both have nice clarity and function for their price. The capped windage, again for my personal taste, is not a negative - nearly a plus. To me, the SHV is the best "bang for the buck" in the mid-priced range of scopes. The 5mil/10moa elevation turret isn't even a deal-breaker for me.
It all boils down to your personal preferences. End use. Ranges most frequently shot at. Reticle utility vs too busy/confusion. Turret ease of use vs positive clicks vs readability. On and on. Too many choices available.
