Sportstick wrote I should have said "better for me". Apologies. There is no such thing as an objective "better". All opinions by humans are inherently subjective. In this case, the difference in climate makes one choice subjectively preferable for you, while the opposite is true here where temperatures can reach 120F in Summer. In my two current BMWs with sunroofs, they are never open, nor revealed by sliding the shade. Never. We particularly ordered my wife's Macan with a steel roof, a choice Porsche offers that BMW should follow. A steel roof vs. a sunroof also increases interior headroom in the absence of the module effectively lowering the headliner, creating another subjective preference difference if one is underendowed with height.
Agree, likewise a proper sunroof is the only choice for me, not a big pane of glass with limited photochromic capability or a gloomy interior.
Other brands can do this, albeit not many choose to do so, unfortunately.
Horses for courses, unless you are BMW.
