To me about the only place for a maxi is on the highway. If you do a lot of long distance riding, they would be great. But in the city, however you define it, you are going to have intersections, stop and go traffic, and lots of turns. You will have to maneuver in tight spots. But you don't have to get a barge like a Burgman 650 to have a cross country scooter. The Vespa GTS300 Super, Piaggio BV300, Kymco Exiting 500 are all smaller very maneuverable scooters with enough displacement to take you anywhere.
