I've shot far more mule deer than whitetail, but I honestly can't tell a difference. Mountain, prairie, or wheat field; mature or young; buck or doe; whitetail or mule deer....I can't differentiate the taste.

I know folks who turn their noses up at whitetail, of any age/sex and much prefer mule deer. I know people who claim the opposite. Lots of people I know can't stand antelope, but like deer. I can't tell antelope from deer either (or elk for that matter).

Lots of variables that have been discussed already can be a factor, but individual taste buds are a biggie, I guess. This is assuming those folks don't just "hate" a specie's taste because they had it force fed to them as a kid or improperly cooked once...
