For me it’s 100% Nextcloud. It was a pain to get working at first (and I’m dreading the day it breaks, if that happens). But it is so much more than just a self-hosted Dropbox solution:
- Maps
- Calendar
- Markdown editor (I’m using this to try and replace Google Drive for collaborative document editing with my friends; most of what we need can be achieved with Markdown formatting)
- I haven’t tried it but there is a Talk plugin that allows for video conferencing in browser;
- a bunch of other stuff I’ve never played with like mind maps, PDF conversion, music player, etc.
I’m not getting Microsoft Office or Apple quality mail clients, or word editors, but the fact that it’s always available to me is enough to make the trade off worth it. YMMV
