It's amazing Quad9 is run as a non-profit org.
I run an email forwarding[0] app and I need to do a lot of DNS query(for spam filtering purpose), I run dnsmasq top load balance between CloudFlare, OpenDNS, GoogleDNS, Quad9 and Hetzner DNS. Quad9 outperform the rest with 2-4x faster and more reliable. In term of reliable I meant they won't rate limit me.
If anyone need reliable DNS, Quad9 rocks it. I'll contribute my part on this battle too.
Thanks Quad9
