This is on my 80 mind you, but the Falken AT's I had were no comparison to the BFG KO2's I replaced them with. I could only handle about 7K miles on the Falkens before I returned them. They slipped a lot on the trail, felt vague on the road, they just didn't feel like a great tire to me. I feel much safer on the trail and in the wet with the BFG's. The guys at the tire shop told me they get a lot of Falken AT's coming back in due to customer dissatisfaction, and I also noticed the Falken's required A Lot more weights to balance them. I think the dollars spent between the two are dollars well spent, and I am a major miser.
The Cooper AT's won a shoot out on Expedition Portal between AT's, and beat the BFG's. I'm not sure if that was the KO2, but I think it was. You can easily Google the shootout, it's worth reading a. I've never tried the Coopers, and I must confess I like a more rugged/aggressive look.
Just my two cents.
