I am happy with the combo after a summer of driving, although it is difficult for me to compare to the just 24 hours I had the Uberturbines on. From what I remember, the steering and handling is a tad less sharp which makes sense given the all-weather tires and increased sidewall, but the trade-off is more than worth it for the improved ride quality vs the 21s.
We have not gotten a real snowfall yet in Michigan, so I can't comment on how well they do compare to real winter tires, but I will say it's nice that they don't feel "mushy" like dedicated winter tires do in 40-50 degree weather. And of course not having to visit the tire shop with the rest of the city in November sure is nice too. If this were a sports car, I would still run dedicated summers and winters, but all-weathers/seasons seem to be fine for a heavy beast like the MYP, which isn't really designed for going around corners quickly with max grip.
Given your situation, I would imagine something like a all-season PS4 may make more sense, but I haven't had firsthand experience with them.
You'll read various accounts of what may get you the best ride, ride quality, and road noise, but I think it's going to be pretty difficult to find a true objective comparison. Once you figure out what class of tire you want (all-weather, performance all-season, etc), I'd just choose whatever is easiest to get/cheapest and I'm sure it will be fine.
Good luck!
