I use it at home, about 3 years running on a small server in my closet.

I think it's hard to beat, but it's definitely not free in the long run - hard drive costs, electricity etc all factor in, your drives will die eventually and have to be replaced and they aren't cheap.

I run it in ubuntu snap because I was extremely lazy setting it up. It gave me plenty of headaches when I wanted to enable some plugins due to snap's security design, so I do wish I hosted it directly, but as far as day to day sync and usage it's been no issue.
