Do you have a question about the scope brand or the magnification? Or both? As for the scope, the conquest is, in my opinion, the best scope you can get in the midpriced scope range. For the magnification, I really ~4X for coyote hunting. Some guys like lower powered scopes for the close in shots (1.5-3X). But I have no problem finding a small moving target in a scope and perfer higher magnification for coyotes. 3.5-10X is a great magnification range for coyotes.
I have a 4.5-14X44 Conquest. I had it on an AR for a short time, but now lives on an Encore. I love that scope!
