Never had a Steiner so I can't give an opinion on them. I do have a Burris XTRII in a 3-15 and an XTRII in 5-25. The 3-15 is clear as a bell. The 5-25 seems great one day and not the next. So, I bought a used Cronus BTR a while back to try...everyone seems to feel it's a toss up between it and the Vortex Razor. Really like it. Enough so that I ordered a new Gen II from Cameralands sale this last weekend. I figure on replacing the Burris 5-25 with it.
