For the sleekest looking top with the least wind resistance a convertible top is the way to go. Sometimes also called Sport tops,  convertible tops attach to the windshield and are low profile offering good protection from the elements  for the forward cockpit. Convertible tops are compact and easily collapsed for storage.
You can add side window panels for more protection and cover the stern with a aft curtian or have an extended rear camper top also.
