Our take: Oral-B iO uses a small round oscillating head and Sonicare uses sonic vibration. Both are well established, so comfort and the price of replacement heads are better tie-breakers than the brand.

Short answer: They rate about the same. The Oral-B iO3 (around £60) is rated 4.4 and the Sonicare 5300 (around £60) 4.3. The Sonicare 4100 is the most reviewed, with more than 57,000 buyers.
