I have a soft spot for Steiner. Super well made, but the T5Xi does not get the respect it deserves. Lots of Razor fans. Both are solid choices. The Steiner T-series has a unique turret design that some really like, and some do not. The numbers appearing through an appature is a little different. The handling of the turrets is very different.
I am working Saturday, happy to take your call personally. I can walk you through some of my experiences, and those of our customers. We are dealers for both brands. We also have a special relationship with the maker of the MSR reticle, or which I am personally a fan of, and maybe even more of the MSR2.
