New car -> All-weather tires or SR+WR if available?

The topic has already been discussed several times and I have already read in quite a bit (all-weather tyres vs. SR/WR). But I hope here for some advice or tips for my special situation. Due to young people we have just bought a “larger” car, a Seat Leon ST FR with 2.0L (190hp). The car is relatively new (EZ January 2019) and stands on summer tyres (Bridgestone Potenza) on the original Seat Leon “Performance” 18″ rims. The DOT is also relatively new… e at least mid-2018 or even mid-end 2018. The car now has about 10000km…how long the summer tires were driven I can’t say, because at least 2-3 months had to be driven on winter tires. For me now the question arises whether all-weather tires (Continental AllSeasonContact or Michelin CrossClimate+) or additionally a set of rims with winter tires. At Seat there is probably just a “offer”, which would be the same rims as the summer rims and rough f are Michelin Pilot Alpin 4, at least according to the offer flyer. I did not find a Pilot Alpin 4, but only Michelin Pilot Alpin PA4 or Alpin A4. What kind of tyre is the “Pilot Alpin 4” or is the name not entirely true and it is meant by the Pilot Alpin PA4? I once attached a picture of the flyer. On this, however, the profile doesn’t look like the Pilot Alpin PA4. But anyway, the tire is no longer the latest generation, right? whether it is really so smart to throw away the relatively new summer tires (with which I have to check how much profile is exactly on it) or sell for practically nothing and then raise all-weather tires. Costs for the all-weather tires incl. pull up would be about 500-550€. The winter complete wheel set is available for 310€ per bike, i.e. 1240€ in total. I’m puzzled what I do best and maybe someone has “the” tip for me here. Maybe the new Continental AllSeaso nContact even “better” than the somewhat more aged Michelin. While saving the change in the summer and winter (apart from the cost of changing wheels) is of course also pleasant. My annual driving performance is currently only 7000-8000km…which can change quickly.
