I'll be honest, I've got plenty of experience with a few Optics, but not a lot of variety of spotting scopes. I've used the Leupold 12-40x a lot.
This year I got to use a buddy's Razor 11-33x a good bit, in a desert environment in varying lighting conditions.
Compared to the Leupold, I was not impressed with its brightness at the higher magnifications. It's enjoyable to glass with, and very clear/bright in the 11-20x range. As you get up to the 33x mark, brightness drops very noticably. Eye relief also got annoyingly short. Eye relief isn't a big deal if you can get set into a comfy position, but if you need to set up and use it quickly at awkward angles, the eye relief/eye box was finicky.
The 33x end would still be very useful to occasionally zoom in and verify details.
I'd reccomend it for someone that has a good pair of binos already, and needs something lightweight, but also lots more magnification than their binos. Again if you plan on glassing with it a ton, you will probably stay around 20x to get a balance of FOV/brightness/eye releif. If you will spend lots of time using it at its max magnification, there are probably better spotters out there.
