Much luck with Hankooks here (currently 5,000 miles into my setup), Cheaper side of the tires and overall very good reviews
I often hear of problems with soft sidewalls on Hankooks however the V2 im running don't seem to have the same issue as the originals, and hold up well in spirited driving, I can't offer my thoughts on Nitto as i've never experienced.
PSS I feel you're paying for the name with the same/similar quality of a lesser brand.
