I use NextCloud for some years now. I hate the syncing which destroyed several files. Another problem is files that need to go together like git source directories e.g NextCloud easily screws that up, my with "lost" the text of her novel if we didn't had backups. Their technology is miles behind OneDrive/Dropbox and they seam to not care but add features that enable them to attract new customers instead of fixing the core. When you need to use Office products nothing beats OneDrive.
