Having used F1 gsd3, PP, uniroyal, T1S, T1R to name a few, the T1S was vastly better than the r version, but I change brands all the time haven't found anything as good as the hankook, the old yoki A008 was very good, pity they stopped it, but even this wasn't as good.
Naming toyo as opposed to hankook just shows the person doing so hasn't used the hankook's, toyo not even in the same league.
