I'll have to wait until my test ends. As you now, I'm currently running dnsmasq with 6 resolvers (3x IPv4 and 3x IPv6), stubby, unbound and dnscrypt-proxy, this to determine dnsmasq's favorite (fastest resolver). The test has started on Tuesday (15/05/18) and I will not touch my pi until next Tuesday, this to get an impartial result.
As you also know, I've indicated the unbound solution is doing very well, and is rapidly becoming my favorite, especially since it handles the DNSSEC algorithms better than dnsmasq.
This is why I've asked @gecko, who seems to be running stubby+DNSSEC to publish his findings. More results, will lead to a better evaluation.
But you're right, I can, and probably will...
