TBH, I doubt anyone notices and if they do practicality comes over the professional look for me. SC have several advantages - you can switch the camera between cars instantly, you can remove it instantly for any other reason you may have, you don't risk damaging your screen separating it from the adhesive pads. The disadvantage is SC's do eventually fall off and have to have the screen cleaned and be re-suctioned. That said, it occurs probably once every 6 months so hardly a major inconvenience. However, each to their own. If you never switch the camera between cars or otherwsie remove it or simply value aethetics over practicallity, then 3m pads are the way to go.
