I only cropped one dog's ears and that was Red Angel's, who was my second dog. It looked good on her, but in hindsight I would have preferred her full-drop ears, which I personally love.
Leon did a nasty butcher job on Stormbringer's ears, which I was always pissed about. Stormy had real thick, nice natural ears that went forward and looked like a "baseball cap" ... and Leon's crude, uneven rendering of Stormy's ears ruined his appearance IMO. Stormy was such a powerful-looking dog that he was impressive anyway, but he looked far better with natural ears IMO.
Anyway, I would never crop any dog's ears again myself, as I think their natural ears look way better and add more personality to their expressions.
