I bought a set of the BFG All-Terrain A/T KO's a little while back, and they have to be one of the best all around tires I have ever purchased. They have very good traction both on and off road. They would get my vote, if we were voting of course. . .
If you want good on-road driving though, I suggest against Yokohama and Mickey Thompson tires. They both make some very good tires for certain types of off-roading, but they have allot to be desired on-road.
