If you would choose

The question is between the Nikon Sporter in Realtree Camo 8x36 or 10x36...or WindRiver Cascade in 8x42 or 10x42. Will be using them in the mountains and plains of CO. for hunting (deer, elk, antelope, etc.) or the Steiner predator in 8x30 $50 difference between them. Also which is better for hunting the 8x or 10x. Thanks in advance
