I kind of wonder how accurate the comparison is. I mean I have little doubt that what's listed is accurate, and that gitea is more fully featured than gogs, but isn't there anything gogs does that gitea doesn't? It's still being developed after all
You can try it out on your own.
There is a specification that says "Be warned that we don’t regularly check for feature changes in other products, so this list may be outdated. "
I've been thinking about a self-hosted setup that has public issues but private code. Apparently Gogs supports this, while Gitea has had an open request for it since 2017ish.
