>It appears 1.1.1.1 also does not pass client-subnet, atleast not by default.

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.
