Best deer in my opinion are sitka blacktail from kodiak. Second would be high country mule deer. With that said, I killed an Idaho September high country mule deer AND a Nevada buck at 10,000ft but it was PJ, mahogany sage country. When I got home, I cut the same steak from each buck and cooked medium rare with zero seasoning. Only difference I could tell was in tenderness. The Idaho buck was a bit more tender. It did however sit on ice for 6 days longer than the NV buck.
I hear people talk about nasty sage brush bucks but after eating dozens and dozens of them I've concluded that some people just arent the best cooks😂
