S1E3 and FK510 are more proven globally as they're widely available in many countries and they're both flagship UHP of their brands.

F1S and MC6 are more for specific localized market hence not much international reviews on those. But based on whatever informal hearsay I read, they're also decent.

Between all these, I'd probably try S1E3 first cuz the previous S1E2 had widely came up well in many comparison tests. In fact this S1E3 won the 2021 tire test from Autoexpress UK, even beating some famous notables like PS4. Considering the much cheaper price of S1E3, maybe even cheaper than FK510 and MC6, it should be an excellent value for money.

S1E series is actually positioned slightly higher than V12E series and the price is also a bit higher. S1E3 is replacement for S1E2, not directly replacing V12E2. I am still hoping later Hankook will release V12E3.

So what size exactly did you get, how much, and which shop?
