I have used both Own- and NextCloud in professional environments and it works fine. I had less issues getting it to work than a Domain-attached SMB storage. It's really important to know what you expect from it, but for a cloud storage & sharing solution it doesn't really have any drawbacks. As with most self-hosted software, you need someone to keep an eye on it and back it up from time to time. If that justifies paying Google to do it for you, that's also a reasonable proposition.
