Most of the threads I've found on other sites (both Reddit and the Synology forums) have basically said "go with Docker". But what do you actually gain from this?

People suggest it's more up-to-date, and maybe for some packages that's true? But for Nextcloud specifically it looks pretty good. 32.0.3 came out 1 day ago and isn't yet supported, but the version immediately preceding that, from 3 weeks ago, is.

I've never done Nextcloud before, but I would assume installing it via the Package Center would be way easier to install and to keep up-to-date than Docker. So what's the reason everyone recommends Docker? Is it easier to extend?
