SURI 2.0 Electric Toothbrush vs Oral-B iO Series 5 Electric Toothbrush

Buy the SURI 2.0 if you want a quiet, long-lasting sonic brush with a small head, a pressure sensor and a UV-cleaning travel case, and you care about recyclable heads. Buy the Oral-B iO Series 5 if you want the round oscillating-rotating head, five brushing modes and app coaching that tracks where you brush. The iO has the deeper feature set and a large body of clinical backing; the SURI wins on battery life, noise and travel hygiene. Owners of the iO rate it well overall but some report gum pain and high head costs, while SURI owners praise the light feel and month-plus battery.

• Choose the SURI 2.0 if you travel often, want over a month per charge, a near-silent brush and a small head for tight spots, and prefer plant-based recyclable heads.
• Choose the Oral-B iO Series 5 if you want multiple cleaning modes, app-guided coaching and the round dentist-style head, and you brush at home where the charging stand lives.
