We now have RT43s (T rated) on two vehicles in our household and they are also my summer tires (H rated?? not sure).
My wife and daughter use them year round and are conservative drivers, and we have found these tires to be excellent for their needs.
I have regrets about buying them for my vehicle as their winter capabilities mean much less to me and they are not much fun for sporty driving, I liked the GY Eagle A/S tires I had before much more. My RT43s are good in heavy rain and what little snow and ice they do see, but they are not good for throwing the car around in dry conditions. I put in a stiffer rear sway bar to improve cornering but the RT43s don't hang on really well when I get aggressive.
