That doesn’t answer it (my fault for not asking a better question).
High end clip-ons like the UTM-X are head and shoulders above everything else… for those who need what a real clip-on offers, which is the ability to go from day to night use or from dark to light environment (lit building interior from dark night outside, dark countryside from lit city, etc.) quickly, without carrying multiple guns, with repeatable precision (not screwing up your zero), and maintaining your ability to use your day gun reticle with its elevation and windage holds.
That’s a powerful and necessary combination of capabilities that can’t begin to be touched… if you will use your weapon in some of those ways.
If you’re simply going to coyote hunt with one night gun, and have no “tactical” uses in mind, a quality stand alone sight will serve you much better (lighter total system weight, better center of gravity, better access to controls, better magnification options).
For the price of the items in question, I’d get a stand alone thermal scope and a handheld scanner, unless the capabilities described above fit your requirements pretty well.
