It depends on a lot of things. Price point. Distance you intend to shoot. Priority of identification...ect
For me I use a thermal to scan that way I don't have to use my rifle. The a night vision scope to clearly identify and shoot. Thermal will pick up heat from a very long distance but, is it a German Shepard or a yote? With NV you be able to tell yote from Fido. Or bill from bob if you need it for that.....
