Much easier to find things when you zoom down and get a larger field of view. I use the bottom of the magnification of my 20-60X Swaro a fair bit. Also the lower end of my 13-30X Nikon. On the flip side I use the the highest power that conditions will allow a fair bit when sizing up sheep, deer, moose and caribou as all have horn/antler restrictions across much of BC, depending on the season. Conditions that affect max power use are mirage, wind, lighting, etc. That all said I ran a fixed 20X Leupold Gold Ring for a lot of years and killed a lot of game using it....and preferred it to my buddy's 25X Leupold. Good luck!
