I used to use Dropbox lightly. When iCloud was introduced I tried it, it sucked, and year or two later I tried it again and I have never looked back.

The only downside in iCloud is that you cannot configure whether you want to have whole folders offline available, but barring that it has been smooth sailing for 10 years or so.

Disclaimer: I share nothing with anyone, and I use it with abour 5 devices and most of the time it syncs fast enough.
