Have been using since 2014. Pretty good, just a tad slow. Make sure to keep it up to date and backed up.

I'm running NextCloud from my home. I set it up once and only run system repo updates. It works flawlessly and requires just about no maintenance.

I've been running it inside of a docker image for a few years now, its been pretty rock solid in my experience.

Setting it up behind traefik and getting cron to work correctly were the only parts that I had any difficulty with. It pretty much takes care of itself now.
