Winter tires – decision support Continental TS850 or Michelin A5

Hello, I need your help in decision-making^^ I need 2 sets of winter tyres. One for a golf variant, and the second for a caddy. So far I had the Michelin A4 with which I was very satisfied with the variant. The A5 is still quite new – in the Öamtc test he did not convince so much with consumption and wear – to what extent one can trust the tests I also not quite know… What do the tire experts among you say: Continental TS850 or Michelin A5? n Michelin would still speak of the 30 Euro voucher for refuelling. According to the test the Conti is better for this.
