Besides response time, the next level of comparison is how well geo-DNS-based services (global load balancing, etc.) support these resolvers. AFAIK 8.8.8.8 gives decent results in most places, though I've seen suboptimal US-centric results from Quad9 in Asia. Support for RFC 7871 (Client Subnet in DNS Queries) comes into play here too.

I always used 8.8.8.8, since I couldn't remember OpenDNS's IPs.

But just found out today that, from Sydney, OpenDNS and Cloudflare are kicking Google's ass for speed. 8.8.8.8 is on par with my ISP-default DNS.

Ever since The Great Comcast DNS Outage of 2010, I've had the OpenDNS IPs burned into my memory from telling so many people.

I like the fact that you can sign up for OpenDNS and customize some of the filtering (ads, spam/malware, etc.) They used to have crappy handling of nxdomains (by default) redirecting you to a website with ads, but I believe that's no longer the case?

Pihole is also a great alternative if you have a spare raspi lying around.

Really, if you have a spare computer of any type. I run it on a VM and it works just fine. It was made for Raspberry Pis but it'll work on any system.
