Versus: two brushes, one decision
Each page opens with the call, then shows the working: specs side by side, three-year costs and who each one suits.
Aquasonic Black Series vs Philips Sonicare 4100If you press hard or your gums are tender, get the Sonicare 4100: its pressure sensor is the one thing the Aquasonic can’t do. If you already brush gently, the Aquasonic Black Series costs about $110 less over three years.
Laifen Wave Pro vs Oral-B iO5Choose the Oral-B iO5 for proven round-head cleaning, an app that maps where you brush, and heads sold everywhere. Choose the Laifen Wave Pro if a battery rated for up to 70 days and $5 heads matter more to you than a long track record.
Oral-B iO2 vs iO3The iO3 for most adults: it adds the light ring that shows green at the right pressure and red when you scrub, plus a Whitening mode. The iO2 is about $50 cheaper and starts on a Super Sensitive setting, which makes it the better first electric brush.
Oral-B iO3 vs Pro 1000: is the iO worth it?The Pro 1000 if cost matters most: about $50 for the brush dental offices hand out. The iO3 (about $110 with two heads and a case) if you want a far quieter brush and a pressure light you can see.
Oral-B iO5 vs iO9Most people should stop at the iO5: the same iO motor and heads, the app and a travel case for about $120. The iO9 adds a colour screen, 3D tracking, seven modes, four heads and a charging case; buy it only if you’ll use those every day.
Oral-B iO9 vs Philips Sonicare 9900 PrestigeThe iO9 for the best feedback on the handle and cheaper heads; the Sonicare 9900 Prestige for gentle sonic cleaning that turns its own power down when you press too hard. Both come with a charging travel case and an app.
Oral-B Pro 1000 vs Philips Sonicare 4100The Oral-B Pro 1000 if you want the most thorough clean per dollar and like a small round head; the Sonicare 4100 if you want gentler, quieter brushing and up to two weeks per charge. Both were about $50 on Amazon US on October 30, 2026.
Oral-B vs Sonicare: which should you buy?Oral-B for most people with healthy gums: its small round head has a slight edge in plaque studies. Sonicare if your teeth or gums are sensitive, or you want a quieter, gentler brush. Our picks are the Oral-B iO3 and the Sonicare 5900.
Sonicare 4100 vs Sonicare 5300Over three years they cost almost exactly the same. Buy the Sonicare 4100 (about $50) if you just want the brush; buy the 5300 (about $75) if you want three modes, a travel case and three heads in the box.
Philips Sonicare 4100 vs Sonicare 5900The Sonicare 4100 if price matters most: about $50 with a pressure sensor. The 5900 (about $90) adds Philips' 2026 drivetrain, three intensities, a Gum Health mode and up to 21 days per charge, and it’s the better pick for sensitive gums.
Sonicare 5900 vs Sonicare 7300The Sonicare 5900 for most people at about $90. Pay about $50 more for the 7300 if you travel (its case charges the brush), want the app or a pressure light you can see; three A3 heads in the box shrink the three-year gap to about $30.
Sonicare 9900 Prestige vs the Next-Gen DiamondClean 9900 PrestigeSame $380, two different brushes. The Next-Gen DiamondClean 9900 Prestige (HX9834) adds a colour display with coverage feedback, eight modes, a wall adapter and Philips' 90-day money-back offer; the original (HX9990) has years of owner history. Check the model number before you pay.
SURI vs Quip: which design-led toothbrush is worth it?SURI if you want a sonic brush with a pressure sensor, a month-plus battery and heads at about $6.33 each. Quip’s Rev if you prefer an Oral-B-style spinning head in a slim handle for about $70; its heads cost far more on Amazon US.
