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.
I only know them because I tried their tooth paste when I was in Germany and they didn't have ecodenta and the packaging looked good. But so far my experience has been good enough to share it, so that says something I guess
Props on USB-C vs proprietary. I currently own a Chinese Soocas brush that I bought only because it has USB-C. It's just so simple. No stupid proprietary magnetic system that stops charging due to copper contact points getting oxidized.
