What tyres?

[Superpep]

Hi all, newbie here. Just about to pick up my first Subaru....23 plate XV SE Premium. Looking forward to it, test drive was great and now thinking of tyres. Car currently has a very odd mixture of two different economy brands (on different axles as well 🤨), plus one Dueler. Terrible. 

My question is, I live very rural....think muddy single track roads, potholes, loose surfaces, soft verges when meeting traffic, steep hills etc etc (rural mid Wales). Replacing a surprisingly capable '63 plate Duster 4x4, but that is shod with proper off-road tyres, so not really suited to normal road driving. 

So, question is what are the best all season tyres that actually work in mud and snow to pop on the XV?
