I wouldn't recommend Quad9 (9.9.9.9) for personal use either.

During some very brief testing I ran into performance issues like 1500 ms response times and UDP timeouts.

This leaves many unanswered questions. What criteria is used to define "malicious" traffic? Who gets to add domains to the blacklist? Etc.
