Nextcloud, after setting it up it gives me everything I love about Google and Apple's cloud services without the privacy invasion or any of the other cons. And I even find it more stable and less buggy. 10/10
Same for me. But there is work involved in the maintenance, there are awkward transitions at times with PHP migrations. But I would not go back to Google. I have tons of storage space without having to pay the associated service fees at the cost of slower speeds.
