I’d say it depends what “best” means. There is Codeberg, Gitea, Gitlab and others. Last year or so they started Radicle (http://radicle.xyz) which is decentralized, but I don’t know how far they are.
The site https://women-in-tech.org may also be interesting.
It’s definitely time for Searx MetaSearch or projects like https://yacy.net/
Gitea looks good. What lets them a bit down imho is that they are using Cloudflare.
