Falken better for autocross, may be greasy when hot to be good for track days. Yoko better in the rain (Neither tire is great in the rain) Yoko would be better for daily driving because of better wear.
azenises are superior in the rain provided the tire can make contact with the ground. i even drove through a freak snowstorm to the tire rack last april on them and they stuck fine. definitely the coolest tread marks on the road!
if you don't abuse them and keep good pressures, you'll probably get 12K-15K out of them
