Pentax, Kowa/Howa, Athlon...even Sightron
Anything ED or UHD does offer an edge at LR for resolution from these brands
Eyepieces matter alot. Variable eyepieces can be less quality vs a fixed mag. A fixed in the 20'ish mag range tends to offer a great image. The Sightron from a few years back had one of the most useable variable eyepieces... no idea on current manf.
Pentax 65mm body is great... variable eyepieces is not. I merged the one from the 80mm spotter but that created other issues.
If the budget allows an ED small body Kowa and eyepiece, live happily ever after.... yes, an eyepiece can cost alot of money.

PS... refer to birding sites for their review on spotters and binos. Optics is their schtick and they are very picky about the same things we need to see game under challenging conditions.
