Its stupid fast, reliable, and rarely has any conflicts. If it does it seems to work them out without intervention. I've tried Nextcloud including the AIO image and its just so clunky and slow. I was getting sync errors just on the simple Notes apps. Repeatedly. I mean I get why people like it, it can do way more than Seafile. But for a pure Dropbox replacement, I love it.

The fact I can reach any file on any device from any other device without syncing EVERYTHING is fantastic. I know Syncthing is also popular, but seems to require more manual settings if you want to be selective on what syncs.

I will say, I've tried and failed numerous times to get Collabora CODE and S3 storage integration to work with Seafile and that is a nightmare, at least for me. I cannot get my head around it. But standing Seafile up itself was fairly easy.

Does anyone else use it? If so, have you tried the CODE and/or multiple storage backend integrations?
