## The top picks

- **Most people: a well-priced sonic brush with a pressure sensor and a two-week battery:** Philips Sonicare 4100 Rechargeable Electric Toothbrush (HX3681/23). Philips' mid-priced sonic brush: a C2 Optimal Plaque head, two settings, a pressure sensor that pulses the handle, a 2-minute timer with a 30-second pacer, EasyStart, and a 14-day battery.
- **A round oscillating head, four modes and app tracking:** Oral-B iO Series 4 Electric Toothbrush with 1 Brush Head. Oral-B's mid-range iO: a round oscillating head with micro-vibrations, four cleaning modes, a pressure sensor, a 2-minute lightring timer, app tracking and a travel case, per the description.

Most people should get the **[Sonicare 4100](https://twelvetabs.com/reviews/sonicare-vs-oral-b/#pick-1)**. It costs less, has a pressure sensor and a two-week battery, and cleans well. Get the **[Oral-B iO Series 4](https://twelvetabs.com/reviews/sonicare-vs-oral-b/#pick-2)** if you prefer a round oscillating head, want four modes, or like tracking your brushing in an app.

We compared a mid-priced model from each brand. Cleaning results are close between the two: independent reviews that Electric Teeth cites find Oral-B's oscillating-rotating action removes slightly more plaque, but call the benefit minor.

## The short version

- **Want the lower price and a long battery?** The [Sonicare 4100](https://twelvetabs.com/reviews/sonicare-vs-oral-b/#pick-1).
- **Want a round head and four cleaning modes?** The [Oral-B iO Series 4](https://twelvetabs.com/reviews/sonicare-vs-oral-b/#pick-2).
- **Want an app that tracks your brushing?** The Oral-B.
- **Want a pressure sensor?** Both have one. The Sonicare's pulses the handle.
- **Want cheaper replacement heads?** Sonicare's are a little cheaper than Oral-B's iO heads, per Electric Teeth.

## How to choose between them

- **Head shape.** The Oral-B has a small round head that oscillates, with micro-vibrations. The Sonicare uses its C2 Optimal Plaque head with sonic vibrations.
- **Modes.** The [Sonicare 4100](https://twelvetabs.com/reviews/sonicare-vs-oral-b/#pick-1) lists two settings. The [Oral-B iO Series 4](https://twelvetabs.com/reviews/sonicare-vs-oral-b/#pick-2) lists four modes.
- **Battery.** The Sonicare listing says up to 14 days. The Oral-B listing says only a long-lasting lithium-ion charge.
- **Timers.** Both have a 2-minute timer. Both split your mouth into 30-second parts.
- **Extras.** The Oral-B description mentions a travel case. The Sonicare listing shows none, and owners say there is none.
- **Price.** The Sonicare costs less today, and its replacement heads are a little cheaper.

## Our picks in detail

### 1. Sonicare 4100: best for most people

**Why it made the list**

- One owner's short run time was fixed by an app update.
- One owner says settings can only be changed through the app.

## How we researched

On October 14, 2026 we read the Amazon listing pages for the Philips Sonicare 4100 (HX3681/23) and the Oral-B iO Series 4. We read each page's bullets and specs, Amazon's review summaries and the reviews we could see. We also read Electric Teeth's Sonicare vs Oral-B comparison and checked Google's top results for this question. AI wrote this guide from that research.

The Oral-B listing gave no battery life or warranty, and the Sonicare listing gave no warranty. The Sonicare 4100 reviews may mix two versions of the product, because Amazon lists a newer version with three settings separately. Three of the Oral-B reviews we could see date from 2022 or 2023. Few critical reviews were visible on either page, so complaints are milder than a bigger sample would show.
