There's also knot-dns (https://www.knot-dns.cz<https://www.knot-dns.cz/>) and knot-resolver (https://www.knot-resolver.cz<https://www.knot-resolver.cz/>). For BGP anycast, a simple health check script and ExaBGP go a long way.

I'm a big fan of NSD as others have commented, but there's some interesting oddities in the way it handles certain events at scale which aren't really something you can easily change, so much depends on what you are trying to do.
While NSD, Unbound and Domain are all from NLNetLabs, they are different codebases AFAIK.
