All we have in this chunk of the desert is mule deer, and they taste just fine. Doesn't get much better than a smoked venison roast from one....I shot my first and only mule deer two years ago. From the time I pulled the trigger until the time we had him skinned and hanging was leas than an hour. It was cool if not cold outside. That deer was the foulest most rank animal I've ever smelled or tasted. I simply could not eat it. It was not spoiled but had the most gamey / musky taste and smell imaginable. Our dog who is part beagle and will eat ANYTHING wouldn't even eat this deer. I felt horrible but most of it went in the trash.
I've been told that sometimes they pick up flavors from what they eat - for example, if you shoot one where there's a lot of sage, it can have kind of a gamey sage taste - but that's second-hand knowledge; we don't have much sage around here.
