Due to the different rules and regulations around Europe in regards of winter tyres, the safest bet tends to be non-studded tyres. This will give you more freedom when traveling across borders.
If you have studded tyres you might end up in situation that you cross borders and you are not allowed to continue driving with the tyres that you have. Non-studded tyres will always perform well during winter conditions and will allow you to drive through countries that have restrictions on studded winter tyres, so you will be more flexible.
