I see them everywhere, but never have actually got to feel how smooth they are. Do they live up to all the hype?

My current wheelset has some butta smooth Campy HF hubs, but I ride them in all weather. So, do I keep what I've got and get some Formulas for the winter/rain, get a Phil set for year-round goodness, or just learn to stop worrying and love what I've got?
