Winter mixed tyres 225/40 R18 & 255/35 R18

The price only plays a role with products that are otherwise equivalent. Unfortunately, the rear axle restricts the selection enormously. I have chosen the following: The order represents my personal ranking, which is based on my gut feeling. Does it make sense to differ in front and back? The tyres of Michelin, Conti and Pirelli are already quite old, correct? The last three seem to have been on the market since 2016 (?). What are the last three of them, of which at least the Koreans are attractive at the price? Which would you take?
