Came from Pilot Sport 5 and tried Ultrac Vorti +, I must say that UV's have WAY better dry grip and feel/handling then PS5's, dry grip right from the get go is very good but once you warm them up, they are crazy! Lots of people say TT RS mk3 (8S) is prone to understeer but with these tires, I never experienced any understeer, mind that I am really pushing my car hard (twisties and highway).
One thing they are not the best is wet, PS5s are much "safer" in both wet braking and wet grip/handling. With UVs I had couple of "scary" moments so I am little more careful when it's wet. Oh yeah, can't forget the sidewall.. UVs have really stiff sidewall and I LOVE IT, PS5s felt too floaty in corners while UVs feel really stable, but sidewall looks of PS5 are on another level compared to UVs.
Comfort is better on PS5 but I don't expect comfort from UUHP tires so i don't really care about that... the wear is definitely higher on UVs, I will rotate them soon because fronts are around half way while rears look "brand new", with PS5s I did more then 20k km and they looked brand new, so wear was insane! but again I don't care how long tire will last because I am after ultimate grip and feel :)
To sum it up:
PS5 if you want boring safe bet tire / UVs if you want grippy direct sporty tire for super good price (that is still safe btw)
