Air-Con or sunroof?

Have had both. Sunroof is great on fine days (if you don't mind the wind noise). On all of the other (non-fine) days the air-con beats it hands-down.
 
Two months ago I would have said Sunroof which I have in my own car. But my son recently got a car with Aircon, which I have taken on long journeys a few times. Consequently I have changed my mind completely in favour of Aircon. Sunroof open on a hot sunny day can roast you.
