Those high price branded tyre generally are good quality tyres! But whether it suits one's car or driving style is another story ! Some not branded tyres can be as efficient and good quality as well! Branded tyres had to be high price, just imagine the money they spent sponsoring F1 and other major racing events ! Used to use premium tyres but recently found one that perform equally good non branded one! 

i agree with you
i almost use cc6 tyres on my car becouz of it lower noisy level
heihei and the price is slighly cheaper than other premium brand of tyre
