I've been though many sets of Revos and can say I like the look, decent traction and quality. Best thing is, they don't reduce MPGs like some other ATs. On my trucks, they last about 35k miles, and I use the milage warranty towards the new ones.
I'm partial to the Cooper AT3. Good looks, quiet, and so far have lasted about 30,000 miles with lots of tread left. Not the best traction in wet weather though, they tend to spin a little when taking off on hills if the road is wet.
