I had a Sonicare, my second one, and I switched to this Oral-B iO 6 and I'd give it 6* if I could. The leap in cleaning quality is huge. The feeling after brushing is close to how it feels after a dental hygiene appointment. I started with the intensive programme (out of habit from the Sonicare), but I've switched to the Sensitive mode and it's more than enough for me.

Done in under two minutes, teeth as smooth as mahogany. It takes a little longer to charge, but in practice, that just means putting it on the charger in the afternoon, forgetting it exists, and taking it off in the evening – a full charge lasts for another several weeks. I don't use the app, I haven't quite reached the mental state where I feel the need to chat with my toothbrush yet.
The quality of the clean is absolutely incomparable to manual brushing.
The coloured pressure indicator is a very useful feature.
Nice to hold, a bit on the heavier side, but that's to be expected I suppose.

I’m happy with it, although I do change the heads sooner than after three months

I wonder why the biggest crap has to have an app. soon the toilet paper will have an app. I don't understand and I won't understand. I don't consider the slower charging a disadvantage, it doesn't bother me.
Processing
The attachment holder could have been a bit better designed, but that's about it.

Unfortunately, the toothbrush leaks from the space between the head and the body. I've tried replacing the heads and still the same problem. I'm sorry, but with a toothbrush for nearly 5.000, - I would not have thought that I would encounter this.
The brush flows in the space between the head and the body
very low battery life (about 6 days)

I am satisfied with the brush. It has quite a few "modes" but I personally don't know the difference. After using it, the teeth are really clean to the touch of the tongue. The difference between a manual brush is really noticeable. But the charging time is really long.
