Cup and Cone hubs are pretty much without equal at the price they come in at.
Only proviso for using them in poor weather is cracking them open when new and filling with a much higher quality and volume of grease and then a semi regular service (yearly for me, only takes half an hour to do both). I've got ultegra hubs that have done over a decade of winter use (6500, bought them not long after launch.) I've also got D-A of the same era that have not had as much bad weather use, but still run perfectly. Both now pressed into service as CX wheels.
Only weaknesses are leaving them with the factory fill (which isn't optimised for bad weather, but for "normal" riding) and the freehub will eventually pop, especially with lots of cleaning/degreaser (unavoidable in the winter!) They can usually be replaced for not so much. Ultegra was about £30-40 last i looked, half an hour or so to swap. Only done it once on my old Ultegras, D-A is still on the original.
Most of the CNC/sealed bearing hubs i've had have either corroded to nothingness (usually a flange failure) or one of the (many) bearings has failed and worn/damaged the shell or axle, which is a 50/50 to putting the hub beyond economic repair once you factor in the obsolescence of the part. Unless you get something REALLY expensive where parts are still available/compatible.
Other issue with factory wheels is that by the time the rim has had it the manufacturer has got bored and moved on, so you either can't get the rim (or it costs more than you paid for the wheels) or the proprietary nipples have seized, and the proprietary spokes aren't available any more........ and the wheel is a write off......
My pick for winter wheels is almost always something like ultegra laced 32 3x to a stock rim of some description, open pro, open sport, a CX of some description, TB14, Archetype. The list is long.
You can replace the rim every two or three years and reuse spokes and hub. I've been doing my own for ~20 years, it's better than therapy
(My ultegra hubs have probably had 8 or 9 rims between them........)
Edit, Ultegra hubs were bought in 1998 and have at least 100000 miles on them, D-A (7700) were bought the following year i think and have around 40000 miles on them, still on the original rims.
