The Oral-B iO 5 is best for best value premium clean. Its key feature is the iO cleaning motor without the extras. Buy it if you want the excellent iO cleaning motor and pressure sensor at a sensible price. Owners and specs point to strengths such as same iO motor as pricier models, smart pressure sensor and quiet operation, while the main drawbacks are iO brush heads cost more and basic screen.

The Sonicare 6500 is best for sensitive gums, with gentle sonic clean with a travel case as its headline feature. Buy it if you prefer the sonic feel, have sensitive gums and want a travel case. Its strengths include gentle on gums, travel case and three modes; the trade-offs are brush heads add up and charging stand is basic.

A pressure sensor protects gums and enamel from brushing too hard. A two-minute timer with 30-second pacing helps you brush evenly. Check brush head prices; they cost more than the handle over a few years.

Both clean well. Oral-B's round oscillating heads feel more like a dentist polish; Sonicare's sonic heads feel gentler. Pick the feel you prefer. Every three months, or sooner if the bristles splay.
