All season tyres - better or worse for all year use?

I've been reading reviews regarding all season tyres . I'm guessing these are a better purchase to summer tyres which I use all year because I can't afford another 4 wheels or 4 tyres to swaps. Does this mean they wear down a lot faster because of the material used to give them the winter grip. Normal winters are only effective below a certain temperature, but are these ones which in Summer are better off with Summer tyres or am I better off replacing all my all year summer tyres with these all season ones?

They are softer but that is due to more rubber in the compound than the usual carbon black, but no reports of wearing fast. If your tyres are worn now, then now's the time to replace with Cross Climates, Weatherproofs, of Goodyear Vector 4 Seasons.
