Sure, when you're right next to it, but I suppose if you're away from home and using your VPN to query your pihole, NextDNS might be faster. But yes I found the dig quite out of place, but for the reason that everyone I know who runs a pihole is not to run their own DNS resolver but (1) to block ads (2) not send more data than required to other services (a strike against NextDNS) (3) tinker, have more control (4) learn

I believe, what they mean is, NextDNS, given its global footprint, is lower latency than pi-hole in your local network connected via Tailscale over public Internet.
Sorry, author here. It got edited down a bit for brevity.
For one user never leaving your house, you're correct.
But once you have two or more users in different cities (or you're traveling), then your Pi at home will almost always lose compared to a geo-replicated service.
How could it possibly have lower latency than something that's literally on your local network? Once it caches a request it's nearly instantaneous.
