PS4 tires are max perf. summer which is the same category as the stock PZ tires. Summer tires work great if the temperatures are above 80 deg. typically and have peerless grip and good rain performance too. Once temps are routinely below 40 deg., they become dangerous to drive on, as the tire compounds become harder, somewhat like hockey pucks if it gets cold enough and you’ll lose traction.
All season tires work well into these temps and are also very capable but slightly less so than summer tires at high temps. All seasons also have some light snow traction, have great thread life, better comfort and less noise. Michelin testing at least for PS A/S 3 showed at around 65 deg. the all season tires outperformed the summer tires on a track already. Where I live in Seattle area, the Pilot Sport All Seasons perform so well, there’s no reason for a summer tire or a dedicated winter tire as temps stay mild in winter or summer.
AS4 will improve your ride (maybe 15% improvement?) however they are definitely still firm and will maintain the sporty feel of your car or improve it even; for me these are perfect and what the MYP should have come with, just as the C8 Corvette does (yes, all season tires for the first time).
There could be more comfort-oriented tires, or you might want to explore suspension upgrades such as UP springs/coils or MPP coils which I am also doing.
Alternatively you can change the wheels for 19 or 20” and get the well-reviewed comfort-oriented
