This is subjective but it does clean better than my previous Oral B (Genius X). New motor has a far less irritating sound profile. The tracked brushing function is still an overkill, I’ve used it only once more for the novelty of it. Most folks will just stop at the brush sessions tracking and maybe some of the gamification parts of the app.
