I dig the Finish Line Wet and Dry ones, depending on the conditions.

Dry for the summer because it's really clean. It doesn't attract dirt at all, and my drivetrain stays shiny clean. The downside is that you have to re-apply it every few days if you're cranking out more than 10 miles a day. It's fast, clean, and very impermanent.

Wet for when it's the way Seattle usually is. Yeah we get 3 nice months a year, and then the rainy season kicks in. Finish Line Wet is great at resisting water, but the higher viscosity has the downside of gathering dirt like a vacuum cleaner. Especially all the ground up cinders and sand that the DOT uses on the roads here during the winter. Gotta clean the drivetrain once a week, pretty much.
