Hi,
All seasons tyres are a good compromise if you only want one set. Any tyres from the premium manufacturers are good, not too noisy, reasonable wear and economy.Cost wise they are more expensive but as you only need one set this offsets it. Always fit a full set, half sets can catch you out on occasions and can be dangerous.
Winter tyres use a rubber compound more suited to cold temperatures and over the years I've tried all makes and find that any winter tyres are better than none. On our workshop van, a Transit Connect, I fitted a set of Falkens all seasons last year and they coped well in the snow but can still eat up the motorway miles. I have a customer whose daughter runs a Corsa fitted with Good Year all seasons with no reported problems. I fitted a set of Nokian winter tyres to one of the local forestry engineers Transit who ran them all year round with no problems, he needed them more for their mudplugging ability than their snow grip. This winter I am fitting some Michelin all seasons to our van but these are expensive at £100 per corner so i'll see how they perform.
It really all depends on what you need and can afford, definitely keep clear of the budget brands as these are just a false economy, but I personally like the all season tyre concept because your always "ready" if the weather turns nasty with no need to change a set wheels/tyres.
The winter tyre demand is a comparatively recent thing here, its only in the last few years that they seem to have come to the fore with many of the fast fit centres actually stocking them instead of looking at you as if you had two heads as once was the case if you enquired about them.
Summing up, "normal" tyres adequate, pure winter tyres good and all season tyres a good compromise.
