They're two totally different tires for two totally different purposes. I had BFG KO2s and liked them on my Frontier. They wore really well, were great in the snow, and were relatively quiet on the highway (they did get louder as they wore)....BUT if I had a more dedicated ORV as you're describing I'd go with the Michelins. They will probably wear just as well, they'll be quieter and they will probably be just as good in the snow and rain.
