9.9.9.9 has twice the latency for me. Why pick quad9 over, say, 1.1.1.2?

Twice the latency for DNS results? Care to give concrete examples? DNS is usually very fast. Twice as long as very fast is still pretty quick, in my opinion.

I'm always on VPN, so latencies add up.

dig +stats @1.1.1.1 www.google.com | grep '[\d]+ msec'

gives me 10-20ms using a nearby vpn server

dig +stats @9.9.9.9 www.google.com | grep '[\d]+ msec'

gets me 30-50 ms, and not rarely >100ms.

Plus DNS caching... I do DOT or DOH (forget which, setup years ago) from my router's local DNS server without any noticeable latency.
