Security	Written in C, bundles patched versions from old branches of system libraries	Written in standard and portable Go
Dependencies	Specific versions of dnscrypt-proxy, libldns and libtool	None
Upstream connections using TCP	Catastrophic, requires client retries	Implemented as anyone would expect, works well with TOR
XChaCha20 support	Only if compiled with recent versions of libsodium	Yes, always available
Support of links with small MTU	Unreliable due to completely broken padding	Reliable, properly implemented
Support for multiple servers	Nonexistent	Yes, with automatic failover and load-balancing
Custom additions	C API, requires libldns for sanity	Simple Go structures using miekg/dns
AAAA blocking for IPv4-only networks	Yes	Yes
DNS caching	Yes, with ugly hacks for DNSSEC support	Yes, without ugly hacks
EDNS support	Broken with custom records	Yes
Asynchronous filters	Lol, no, filters block everything	Of course, thanks to Go
Session-local storage for extensions	Impossible	Yes
Multicore support	Nonexistent	Yes, thanks to Go

Advanced expressions in blacklists (ads*.example[0-9]*.com)	No	Yes
Forwarding with load balancing	No	Yes
Built-in system installer	Only on Windows	Install/uninstall/start/stop/restart as a service on Windows, Linux/(systemd,Upstart,SysV), and macOS/launchd
