I have both and to me it is simple, If hunting at extreme range where the animal is going to ignore what you are doing and it is to open for a stalk then setting a Turret is fine and will give a bit finer accuracy. I live where most shots are 20 to 70 yds and on rare occasions I have gotten a 200yd shot down a tractor lane or ATV track which is where I use the BDC. They are both excellent if you use them the way they were designed for.
