Someone is going to point you to the Tyres FAQ thread and as I'm up early, I suppose it will be me!
To answer you more specifically, I have an Adventure. It came with Metz. Tourances, I swapped to Conti TKC's because I thought I might need them last December, (crossing the snowy wastes of the Pyrenees. As it happens I only saw snow at a distance!).
Since then I've kept to TKC's and in 10,000 miles I'm on my third rear and second front (both recently fitted).
They are ok in the wet, they will react to studs and over-banding in the wet a bit like some pre-radial (biased-belted) tyres used to. They will skip off the stud but will grip the tarmac. If you have never experienced this, it is alarming at first but you soon realise it feels more dramatic than it actually is. The rear will square off quite quickly if you spend a lot of your time on dual-carriageways etc. and the front can 'cup' quickly in these circumstances too.
If you avoid major roads whenever you can and take to tracks and trails they will give you a lot more confidence than the more road biased alternatives. If the tracks get muddy only a true "knobbly" is better.
Tyre choice is a bit like bike choice. It's a personal thing. Get the tyre that suits your use of the bike and what you feel comfortable with.
