I'm a dentist with 4 decades of experience. You don't need all those electronic bells and whistles. Oral B Pro 900 or Pro 1000 is great.

I had my Oral-B (type 3764) for more than 10 years. Never noticed any mold issues, except a little bit of mildew at the base which is easy to clean. I also don’t really put any extra care into cleaning it

I have a 3757 which looks the same as yours but is much cheaper. It probably is legit the same toothbrush with yours having some marketed extra to push the price point 4x higher. Mine is always dripping water so I bet my handle has the same problem

I don't recommend the brush heads with the little yellow "flossing" paddles. Beat the hell out of your gums.  Whether you get the pro or the iO you'll want to use soft bristles. I have an io myself. I like it, but it's true that mold is a concern. You have to stay on it.

So with oral B becoming more expensive. Im looking at other options. Ultrasonic isn't very good at cleaning in my opinion, im hanging onto my oral B pro but the battery only lasts a few days. Suri would be great as I could otherwise replace the battery... any reccomendations for the best of both worlds? Something with a rotating brush head and a replaceable battery?
