Fair enough, but most users won't care enough look it up and use 9.9.9.10 instead of 9.9.9.9 if they want better performance in exchange for allegedly lower privacy.
It appears 1.1.1.1 also does not pass client-subnet, atleast not by default. Queries to my authoritative from Google always includes client subnet, OpenDNS required request for whitelist. For Cloudflare its unclear.

Wow, this is actually a huge issue. Just as a simple test, I tried nslookup google.com for both 1.1.1.1 and 8.8.8.8, and Cloudflare's responses ping at about 200ms, whereas Google's responses ping at ~10ms.
That also explains the abnormally low response time of CloudFlare's solution compared to the 2nd and 3rd place solutions; the geo-location lookups require more time to reach and resolve a decision and thus represent an increase in response time from the resolver (in exchange for improved latency in all future communications to the target server).
If you have a CF PoP close to you, the absent of it shouldn't really matter. Will only have an effect for those with a Google peering much closer than CF peering.
