28 Gator isn't that much faster than 32 Michelin City with Protek Plus. Perhaps 1 mph edge on very smooth road with the Continental product. I run 32 City front, and 28 City rear @ 60/65 psi (150 lbs rider) for comfort. A larger contact patch improves handling around town. Too high of a pressure results in a very small contact patch, which may increase the chance of a flat.

The Michelin should outlast the Gator in mileage. It also excels in the puncture resistance department.
