I've got 28mm 4Seasons on one bike and 25mm Duranos on the other (the Etape version, but I think they're identical to standard Duranos, but for a natty Yorkshire rose logo and some yellow writing on the sidewall).
4Seasons - circa 3,000 miles, 1 puncture, quite a few nicks and central area starting to flatten off.
Duranos - circa 4,500 miles, 1 puncture (well, 2 but one was a pinch flat that was entirely my fault so I'm not counting that), one nasty nick from a piece of glass but otherwise tyres look almost like new.
So I'd happily recommend either/both of these tyres for winter training/commuting. The 4Seasons definitely give the better, faster ride, but they wear quicker. I'll probably be looking to swap them after another 2,000 miles max. Barring any nasty gashes I wouldn't be surprised if the Duranos are still going after 10,000 miles!
Now I've got a SS bike for commuting any rear puncture will be more time consuming to change, so I might go for some 28mm Durano Plus on that in the new year, though I expect them to be a fair bit more sluggish than the 4Seasons.
