I've had folks say they hate antelope, and other say it's the best meat they've ever had. My experience has been that much of how the meat tastes is dictated by what happens to the animal before and after the shot.
Scenario 1. You've been chasing an antelope for several hours, and finally catch up and drop him. He is hot and full of adrenaline. So you gut him and throw him in the back of your pickup on a 70 degree day, where he sits for hours or more until you get back home to skin and quarter. This antelope will taste like crap.
Scenario 2. You see an antelope feeding and with a proper stalk drop him without him even realizing you are there. You have him quartered and on ice within 20 to 30 minutes. This antelope will taste great.
Same antelope. Either kept good or ruined by the hunter's methods.
