Codeberg the community is very nice with strong focus on the right to privacy and free software, which I feel reflects itself especially in a lot of copylefted projects on the service.
Codeberg the collaboration platform is in my epxerience by the simple fact of critical mass quite a bit less ‘collaborative’ for many projects. There’s a couple projects with tight communities, and a lot of single dev projects with maybe a drive-by PR.
Codeberg the software runs on Gitea (/Forgejo) which is wonderful software - slim, simple enough to get everything done without being in the way.
There’s efforts to open up the gitea/forgejo forges to federation, which would be a very neat way to fix the collaboration issue and is - in my view - the way forward for open, decentralized collaborative software creation. It’s still quite a ways off (especially from bring mature enough to be used day-to-day) but when it gets there platforms like codeberg will be the first to adopt it and to also benefit massively from it.
Additionally, at least for my use-case btrfs benefits me since it is less picky about drive sizes being the same and duplicating everything correctly - letting you essentially just throw additional storage at it as you acquire it.
