I've had S20, S21, and now S22. Loved / love them all. Marketing says S22 are better than the predecessors, though I never had problems. I am at the slower half of the B group.

S22's are great.
Rs10's are better in my opinion.

I didn't want to go into too many details, but yes, I actually have RS11 front now. I mounted it for the track day and will replace it with the S22 from the set I bought when it is worn out, this way hopefully reaching end of life of two fronts and one rear around the same time. But I never had any problems with S22 for everyday riding. Haven't tried Q4 yet. (I live in Seattle, with some almost vertical streets, often wet)
