It depends on how much and what kind of wheeling you do. I have the Bridgestone A/T Revos on my truck that does little off-roading and had the BFG's on my '89 XJ (miss it) with 31's that did some mud and some easy trials(I was 16).
Here are the pros of the Bridgestones: 50k mile warranty (I have 30k and they lood brand new), great on dry and wet pavement, good handling (31's on my truck), and quiet.
Here are the cons of the Bridgestones: OK on ice or light snow, clog up real fast in mud and heavy wet snow and basically become street tires.
In my opinion the BFG's are a better tire for off-roading and the Revos are better for street use.
