It must be a seasonal thing, 'cause if you asked the same question a month ago, people were coming out of the woodwork extolling the virtues of Bushnell's big Elite Tactical scopes (DMR, HDMR, ERS, XRS); good glass, rugged, repeatable, accurate tracking, Bushnell's unlimited lifetime warranty (they don't even ask where the scope came from, just fill out the form and return your scope). In the last month at least one shooter compared a Razor 5-20 to an XRS and said the Bushnell was BETTER to his eyes, and so he sold off the Razor.
Here's my experience.
I bought an HDMR (DMR with Horus reticle) with an H59, used, for $1100 (a steal for a Horus H59 reticle).
The glass was about the same as my Elite Tactical 6-25x50 (as it should be, I believe it's the same glass and coatings).
The focus went down to 25 yards (they now bottom out at 50) so it must have been an early one.
Eventually, I sold it back to the seller, as the reticle was a bit busy for me and I'm more of a dialer than holder, and he was kicking himself for selling it (another Hide member).
I bought a new DMR with G2DMR reticle.
To my eye the glass was a little better, just a little brighter, in lower light conditions.
I found my buddy a DMR with mildot reticle for $875 (!) shipped here in the classifieds. It was in like new condition. I've never seen him so elated as the first time he shot with the scope, since he'd never had anything nearly that nice (ex-army with lots of weapons experience). I think the glass in that was the best I've seen in one of these, and chalk it up to illusion or variation within different examples of a model (manufacturing variation).
I have an XRS that I bought from a member here, one from the original group buy.
I would rate the glass the same as my DMR. The XRS has nearly the FOV of the DMR at the bottom end (4.5x with no tunneling vs. the DMR tunneling below 4x) and a good deal more magnification. A lot of erector travel (internally 31.4 elevation and 20 or so windage to the DMR's 34 and 34 mils), 10 mils per rev, locking turrets, zero stop. The turrets track well, the clicks have some slop as a result of the locking mechanism but they're not bad, the zero stop has given a few shooters trouble getting it set but I've not had any trouble.
The XRS pulls off 24x really well but above that it can get a little dark if the target is in the shade. The resolution is fine at 30x but it may not be as efficient (bright) as the alpha scopes. I usually run it no higher than 24x or so unless conditions permit (bright, no mirage). OTOH I was shooting with a new Steiner 5-25x56 today and of course it tops out at 25x, but it was a little darker than I'd like at my local 150 yd. range, too.
I don't think you'd be terribly disappointed with a DMR or XRS, but I'm not sure how I feel about paying $500 more than a DMR for an ERS just to get 10 mil/rev and zero stop (according to the specs, the ERS tunnels at low power, too).
Look in the classifieds for nearly new DMRs and XRSs for sale at a few hundred off list. If you don't like it, you can sell it at nearly no loss, and with the lifetime warranty, it's practically no risk.
