Honestly as far as I'm concerned the xcr offers everything the stag does, but in a far more modern and refined package. Again I don't know if the same accuracy is possible, so if you plan is an ultra accurate, long range semi auto rig - maybe go Stag, but for anything else I would take the xcr every time. The ergo's are amazing. They're the one gun I don't do anything to. No bad lever, or ambi short throw safety, or aftermarket charging handle; everything's perfect out of the box. Non recip charging handle, full monolithic upper with uninterrupted pic rail, folds out of the box and is fully functional while folded. Would be nice to have more trigger options, but it's probably the best factory trigger I've used, and I've heard RobArms has recently been looking into more aftermarket trigger options for their platform.
Dead nuts reliable (in my experience, and with cheap surplus/steel ammo). I've played with the stocks, but I just like variety in that respect, and they pop on and off with one bolt so it's super simple. You can still swap uppers just as easily as an AR can, with the added benefit of swapping barrels too.
Personally, I think these are highly underrated in both Canada and the states. A youtube channel called Small Arms Solutions has reviewed almost all the high end modern semi's and even did one on the xcr platform. He had the same opinion; that the XCR was highly underrated and unfortunately seemed to be the industry's "best kept secret". I would have been skeptical of his opinion if that was the only video I'd watched, but I got a bit sucked in and watched a bunch. He knows his stuff. Definitely worth a watch given there's an apparent lack of reliable reviews on the XCR out there.
I have more than my fair share of modern semi's, and the XCR would be the last one I'd let go of. Not in terms of rarity or collectability (not particularly hard to replace being an in-production gun), but as a do-all gun that's still one of the most fun to shoot. ie if the government could actually take away all but one of my guns, this is the one I would hang onto.
