I am 6'2" and if I do not have my seat slouching a bit, I can bang my head on the sunroof. This is annoying for a vehicle with a fairly large inside. If I had to pick, I would choose not to. I do open mine from time to time, but the added weight at the worst point in the vehicle in addition to the possibility of it breaking is more than it is worth. Also, just know most vehicles given to magazine to test do not have a moonroof, either.
