Need to see the scratch test videos first but okay. The same guy who scratched up the Note7 which only got to Level 3.
Personally, I don't give a damn anymore. Temporary gadgets in a temporary life to worry about petty things. Will be disposed again in a couple years. I don't plan to hold a museum in my household with any of these phones that breeds OCD. Keeping it mint is doing favors for your future buyer who is likely some random stranger.
But my feeling for matte black goes up from 55% to 60%. I also want to see a scratch test on that. If the jet black has same color underneath, I would rather get that one. Matte black will likely show a different color being aluminum like a scratched up slate iPhone 5. That's uglier to me. Scratches should have SAME COLOR underneath.
