Oral-B iO Series 9 - best plaque removal in clinical studies, excellent pressure sensor, and the most useful companion app.
Philips Sonicare ProtectiveClean 6100 - sonic technology is gentler than oscillating, with a very sensitive pressure alert.
Oral-B Pro 1000 - same oscillating technology as pricier models, proven plaque removal, available for under $40.
We compare brushing technology, pressure-sensor clarity, timer behavior, mode usefulness, battery expectations, replacement-head cost, app value, and sensitivity feedback from recent owners. Toothbrush rankings favor the handle that best fits the buyer's brushing habits and gum sensitivity.
Oral-B uses oscillating-rotating heads (8,000-9,600 OPM with pulsation) which are clinically proven to remove more plaque than manual brushing. Philips Sonicare uses high-frequency sonic vibration (31,000 strokes/min) which is gentler on gums and better for sensitivity. Both are significantly more effective than manual brushing.
Over-brushing is a leading cause of gum recession. A pressure sensor that alerts or stops the brush when you push too hard is the single most valuable feature for protecting gum health long-term. All of our top picks include this.
Replacement heads run $8-15 each and should be replaced every 3 months. A 4-pack of off-brand heads costs $10-15 and works fine for Oral-B round heads. Sonicare heads are harder to source at a discount. Factor in $40-60/year in brush head costs when comparing models.
Two-week battery life (at 2x/day) is the standard for premium models. Budget models often last 4-7 days. A USB-charged handle is more convenient for travel than the older inductive charging stands.

Oral-B Pro 1000 is usually the best first check because compatible round heads are widely available in cheaper multi-packs.
Yes, iO heads usually cost more than older Oral-B round heads. The iO5 can still be worth it for better pressure feedback.
It matters if several people share handles or you hate subscription-style upkeep. For gum sensitivity, pressure feedback can matter more.
