From my experience, the Goodyear Wrangler Duratrac is probably the best AT i've ever used in just about every condition besides rockcrawling.
The Duratracs are great on road, and fantastic in the wet/mud (and have the mountain snowflake for snow etc). I mention the rockcrawling because the sidewalls can get dug up fairly easily on sharp rocks compared to the BFG K/O2's. I also got about 45,000KM of VERY hard use out of a set of Duratracs (265/75/16) here in Jamaica, mostly traffic and mountain/offroad.
I recently switched over to Kumho MT51's mostly because of price, was on special for less than half the price of the Goodyears and easily sourced locally and they are fine, but don't provide quite as much traction and on-road handling.
A lot of guys in Jamaica with newer Toyotas tend to run the Maxxis AT980 as a sort of "budget BFG K/O2 equivalent". The tread pattern between that, the General Grabber AT and the BFG are remarkably similar.
