I can second that, I've been using seafile and Baikal for about a year now coming from next cloud. The systems are so much smoother and less resource hungry. Next cloud is good when you have a small company, which I don't think applies to many self hosters.
I have everything inside a docker compose setup, so everything from backups to updates is much easier, and with a nginx proxy and proper network isolation I don't have security concerns with running smaller tools such as Baikal on my machine.
