I never understood DOH over DOT. It makes sense if you want to hide DNS lookups so that people cannot block the DNS queries to ad and other scam networks.

My ISP (my area is serviced by 1 more but they offer lower speeds) blocks the DoT port. They cannot block 443. If they start blocking popular DoH domains, I can use any of the mirrors or run my own over https://wongogue.in/catpics/

DOH prevents malicious network providers from blocking DOT traffic to enforce their own DNS services for “efficiency” reasons.

Most ISPs just want to sell your data and with encrypted client hello and DOH they’re losing visibility into what you’re doing.

DOT picked an odd port, DOH uses 443. Otherwise they both have the benefits of TLS.

DoQ is better than either dot/doh

It's both. In oppressive countries (Iran, China, Russia) where all traffic is filtered, DOH is supposed to help keep things concealed, too.
