I have an Oral-B which has been going strong for a few years now and the battery is still good for a about two weeks between charges, though I actually think I prefer Boot's (UK pharmacy chain) own-brand replacement heads to the official Oral-B ones. It also has Bluetooth which works with Home Assistant because I have a genuine problem with wanting to automate/log all the things. I mean, there's probably an app too but I'm not dicking about with that shite.
