Continental ContiWinterContact TS850 vs. Nokian WR D3

Servus people, I’m already looking for new winter tyres for next winter. Have read some reviews and stand now between the above mentioned tires. Dimension would be 225/50 R17 The most important thing for me is actually the grip on snow (and grip on wet), because with us is always a lot of snow and I live on a steep mountain and it is very difficult for my 5s to come up there, because only rear drive. Both tires have cut very well on snow, b in me, however. Conti : 116€ Nokian: 95€ Hope you can help me with your experience Greeting Jason
