I've run both the BFG A/T KO's and the General Grabber AT2's on a Jeep. The BFG's had a slightly harder tread compound than the General's. The Generals were just a hair softer/more pliable. I found that I didn't like the BFG's in the snow as much as I liked the General's. As for on-road and highway manners the BFG's inched out the Generals here. And I found the BFG's to last longer with tread wear. However in off-road driving I found I preferred the Generals.
Overall I prefer the Generals due to cost, off-road manners and winter capabilities. However, if I lived where it never snowed I would probably lean towards the BFG's.
Just my $.02
