I don't have any experience with either on the Jeep, but I had the BFG ATs on my old Blazer. They were good tires and wore evenly, but I personally can't stand the look of them. The Duratracs are one of, if not the best looking AT tires out there. And they are generally regarded as one of the best performing ones as well.
That being said, like the previous poster, I also run the Falken Rocky Mountain ATS tires. Really like the look of them and they ride great. And they were $350 cheaper than the Duratracs in the same size.
But between the two you mentioned, Duratracs hands down for me.
