So far, I prefer hybrids.

This was my commuter until it was stolen:

Early 90's GT Vantara, with riser bars and thumb shifters.
38mm slick tires.
Reasonably fast, comfortable both for riding and towing and stop-and-go.

This is my commuter now
Early 90's Giant, with a riser MTB stem and cruiser bars and a thumb shifter for the rear (front still on the stem shifters). I very much want to put larger tires on it.
