Not sure what your budget is or how widely available these brands are but I like ecodenta ( https://ecodenta.nl/ only Dutch?) and the humble co (https://www.thehumble.co/).

Currently using a braun/oral-b one myself which I plan to use until it breaks, but I can share with you two companies I like are smyle (https://wesmyle.com/) and smile brush+ (https://smilebrushplus.com/ only German apparently), but haven’t a clue how good they are.

I heard people satisfied with Philips electric tooth brush, but haven’t used it myself.
