I just spent a couple of hours comparing the 10x32s to the 8x32s and to the Zeiss FL T* 10x32. I used a Monostat monopod and Stoney Point Binocular Rest to eliminate steadiness issues.
The short version is that the Sightron 10x32 are excellent. Pretty much the same as the 8x32, but at 10x32. The 8x32 has a slightly more comfortable view and more depth of focus. This is mostly just the difference between any 10x32 and 8x32, though. An 8x32 has a larger exit pupil and more depth of field. The Sightron 10x32 has a little more resolving power than the 8x32, judged by reading distant signs.
The big surprise was the comparison to the Zeiss. There wasn't nearly as much difference as I expected. The Zeiss have a larger AFOV, but the image quality wasn't dramatically different. I'm sure a good technical review would show considerable difference, but it doesn't really jump out at you.
I came away pretty impressed with the Sightrons. I think they are a great value for the dollar, if you want a 10x32. The general consensus is that 10x32s are hard to do well. The high end ones like the Zeiss are great, but cheaper ones usually aren't. I don't see much to complain about with these.
I wish someone would do a thorough review to confirm all this. I'm not set up to do a detailed technical review.
