First of all, a set of wagon wheels from 1700's handle better than the stock Duncraps. They are junk!
BFG's are good off-roaders, but do not handle as well or ride as comfortable as the Bridgestone REVO's. Also, the BFG's do not wear as well as the REVO's. If you're just going to be in the shallow snow, REVO's do really well. They bite and bite. So do the BFG's. I believe in this department (light snow) they are both the same. But if you will be on-road, REVO's win, hands-down.
For right now, I'm going to suggest REVO's. Best tire I've had to date. On my next set, I am going to try out the Nitto TerraGrapplers, but I haven't tried them out yet, so no review. They are cheaper than the REVO's, though, so a big plus there.
