I think the biggest decision to make is whether you want a chassis-style stock with a vertical pistol-grip or a more traditional stock. I've had a few chassis-types on a few bolt action rifles, including an Oryx on a 783, and I just don't care for the whole swing-your-thumb-under-and-around-the-stock thing if you like using your thumb to operate the safety. Just personal preference; the shooting position is fine, but I use every gun I own for at least some hunting and I would find this maneuver awkward in the field. I see some of the TV and YouTube experts seem to like completely releasing the rifle with their shooting hand and operating the safety with thumb and forefinger. I think it's ridiculous, but if you like that method then the pistol grip would be fine.
The traditional stock lets you move your thumb to the safety quickly, comfortably and with minimal motion. I prefer it for that reason alone.
I have also used the Magpul Hunter and the KRG Bravo; they're the best of both worlds. They have the nice vertical pistol grip, which is very comfortable if you are on the gun for extended periods, but your thumb still has unimpeded access to the safety. I haven't tried one, but the XRS looks good in this regard as well.
Finally, if you do much shooting in cold weather...think "coyotes"...then stocks like the MDT's, Oryx and many others have a lot of metal that becomes very cold and very uncomfortable...very quickly.
