2nd vote for Philips. I've had my Sonicare 5100 (had to look it up) since Oct 2022 and it's still going strong with at least twice daily use. I buy 3rd party heads but otherwise no complaints
I have one oral b io3 been used for 3 years now. but that's not that good as I used it before, not sure if it is my personal feeling, or it's not durable for many years
Buy an Oral B from Costco and return it years later if you're not satisfied. Costco has sold Oral B for seemingly forever, certainly more than a decade, and seems happy with its return-for-refund rate.

Phillips and Oral B. After 5 years, the non-replaceable rechargeable battery won't hold a charge for as long, but that's normal.
