This is where the more expensive premium tyres come into play. In the dry performance differences are small and mainly under braking.
But in the wet a budget tyre compared to a premium tyre are worlds apart in performance. I noticed this on the MPSS in the wet, the grip is unreal as is how progressive they are towards the limits of grip.
We have a lot of wet weather, so I find it crazy why people fit stuff like Nankangs, Falkens and other cheaper tyres which simply don't grip, brake or handle even close to more premium tyres. Even more so the more expensive rubber tends to last longer too, which removes the excuse of initial cost.
The MPSS blown me away, 10 track days, 10,000+ road miles, rears are hovering around 3.5mm and the fronts 5mm. That is simply beyond believe as they have lasted close to 3x longer than I could have got out of a set of competing tyres. My next tyre is an R-Comp, but once they've worn out, I shall be back on MPSS.
You are spot on. I've still yet to have any dry weather yet (lovely north east weather), but the confidence that these tyres have given my in the wet is unbelievable. Also the Falken's barely lasted 10k miles (I think they actually have only done 8k). So complete waste of money. I fully expect the Conti's to outlast and certainly outperform them. However they are already making me take every corner much quicker, just to test them out, and give me a every time. They just grip, and never let go! I doubt I even have the confidence to push them so far that they will eventually give in!
