To me they are all tasty. Of course I am not a professional chef, but I do prefer a younger deer for better eating. I am not really picky in the woods though. I usually try to fill my freezer with a doe, and then hunt my buck, but I also enjoy eating the buck as well. As far as portioning deer as far as size and fat, never even thought about it. I am not very picky. When that deer comes under my stand I generally dont have enough time to check out his or her characteristics, just to many other things to worry about for me. Shot-placement, shot opportunity, wind, distance, set up, draw bow back, just to busy concentrating on making that shot count. Just my opinion
