Sonicare or Oral-B — which is better?

Both clean well, and the differences are mostly mechanical preference. Reviewers and dental-community threads tend to recommend Sonicare's sonic vibration for people with sensitive gums (less aggressive on tissue), while Oral-B's small round oscillating heads are favored for plaque removal at the gumline and around tight spots. Several BuyItForLife threads note that hygienists recommend either brand as long as it has a 2-minute timer.
