Depends entirely on the style of hunting you plan on implementing.
When I hike into the mountains sheep hunting, carrying a 45-50 lb pack and 10lbs of rifle, I carry Swaro 8x20mm pocket binoculars. I also have an 18x riflescope, my partner has a 24x riflescope, and I carry a 15-45 power Zeiss spotting scope. The 18x and 24x riflescopes have crystal clear optics/resolution at maximum power. A lot of fine detail can be seen simply thru these riflescopes across a solid rest. The binoculars are used for scanning the country/mountains. Riflescopes and spotting scope for a refined view.
I have 8x30 Swaro binoculars I'll use if I'm not packing as far. I'll still have 18x or 24x scope power for refined examination of the animal.
What other glass are you packing, how far are you walking from a vehicle/horse/camp where you're on you're own, and how much weight/volume are you packing?
I couldn't decide even for myself without more information.
