Never ridden the Zoomer, but I've always been intrigued.

Still, for the same amount of money, get the Super8. Just the right size, with bigger wheels than other heavy scoots, so it's more stable at speed... lots of get-up and go from the engine, and it's fun, whether stock or modified. About the only thing I don't like is that fuel economy is marginally worse than the injected scooters from Japan, thanks to the carb.
