Michelin has been running PS2 and PS3 side by side as equivalent tyres in different dimensions. According to Michelin themselves, they are the same performance category, but PS3 is supposed to have better performance in wet conditions. That is also my experience from track driving.
PSS is a rather different tyre, bordeline competition compound. In some racing series, it is ranked together with true R-compounds. It has not replaced the PS2.
