The old vredestein fortezza tri comp used to be my favourite.
I haven't tried their direct replacement, the fortezza senso all weather, but i've recently put some of their open tubulars on. They're absolutely excellent, like the old vittoria open corsas, but with grippier rubber. I've been running challenge tyres for the last 4 or 5 years and they tend to be less grippy in wet weather and are absolute pigs to fit. If you want a nice fast 25mm winter tyre maybe open pave?
I like vittoria rubino for tough-ish tyres. avoid challenge strada, they are nice but fragile.
I had some vredestein all-weather something a few years ago that were faultless and ok rolling.
