I used to run Yokohama's, I really dislike their sidewalls. They either cracked, bubble up, or just were overall very weak. Had to replace about 5 of them. I have no problems with my Toyo's. They are one of the best tires I've used and heard about. Only thing is they are somewhat harder to find.
Kumho's are also a quite surprisingly good tire...but just not for the winter.
