I'm in the camp that Listerine is bad for you...Sonicare is same. First, it likely does do better job in short term, but because it has much higher strokes per minute versus other brushes. But why use an extreme tool in your mouth.
First, a dissection of your proposed fallacy: A is bad, B is similar to A, therefore B is bad. See the problem?
Second, the Sonicare is not about strokes per minute, it's about using high-frequency vibrations to disintegrate nascent plaque deposits so they can't build up.
My dental visits have been reduced to 15 minute affairs due to a nearly complete lack of plaque, and gum recession has virtually disappeared, since I started using a Sonicare several years ago. Granted, I don't always have time to fiddle with it, so I typically use it about three times a week in the evenings and do a conventional twice-a-day brushing otherwise. But it does work and most people in any field of dental hygiene recommend it or one of its competitors.
What were you saying about fake news?
