I personally switched from NextCloud to Syncthing.
Syncthing:
- is easier for me to maintain,
- allows for the “server” to be behind NAT,

On the other hand, NextCloud:
- gives me a way to share files by link with others,
- lets me browse files via a web interface,
- mobile app lets me access files as I need them instead of having to synchronize everything.
I always go with the following strategy:
