Bot the Steiner t5xi last spring when the burris xtrii was backordered everywhere. Later in summer got the xtrii. Both are 5-25, the Burris is 50mm and the Steiner is 56mm. The NF is 5x20 - 56. However, both the Steiner and Burris are FFP, the NF is second. The Steiner and Burris are also both 34mm tubes, the NF is 30. IMHO, the SHV isn't in the same class as the other two scopes, though being a 30mm tube it is a few ounces lighter. More comparable to the Burris Veracity which is also lighter, but available in FFP. Glass on all is great, but somehow the Steiner seems a bit brighter and the reticle a bit crisper at high magnifications. All are great scopes, so it's a matter of personal preference. Since I prefer FFP in virtually all situations, the SHV wouldn't be in consideration for me. For a few ounces lighter and significantly less money, my sheep hunting choice would be a Veracity over the SHV. But, for day pack hunting situations, I go with the Steiner. Burris service has only been needed once, but it was outstanding. Hear great things about NF in that regard too, and both have outstanding warranty.
