I'd say it depends on your other commuting options when the weather sucks. I biked all winter but on the icy days drove, mainly b/c while I might be fine on studded tires, I don't trust the idiot locals here in VA, for whom a snowstorm is another excuse to drive like jackasses in their SUV's.

I don't know what I'd pick out of those two bikes, but I'd lean towards the one that'd make me happier most of the time...
