Which is the best DNS encryption, DNSCrypt, DoH, DoT?

I don’t know which DNS encryption is best for DNS encryption, DoH, or DoT. So please tell me! What’s the best combination of DNS for iPhone and Linux? I want to use the Adguard Pro app on the iPhone, the dns-crypt tool on Linux, the Adguard provider, and the server to use Pi-hole.

A post was merged into an existing topic: DNS-over-HTTPS (DoH) vs DNS-over-TLS (DoT), which do you prefer?
