Personally, I have no preference, but I WOULD like to have an avatar/actor in the cockpit, that I can see when sat in the seat.
So engine switch on would have my 'virtual' hand reachinf forward and pressing switches on the panel and then setting hand down on throttle and other onto stick.
That for me would be far more immersive than moving a pointer aorund a 2d image to click it on.
So give us a first-person POV actor in the cockpit that makes it look like it's not a ghost plane flying
