ISP DNS servers will always be closer, eg have less latency then third party DNS servers. And after one query, the result will be stored locally, eg no DNS servers will be used for following lookups. The thing with expensive DNS solutions is they only speed up the very first lookup, which might be cached on your ISP anyway. DNS is already a distributed system, which is much larger then any single private entity. Some third party DNS services might also sacrifice resiliency for performance, they will for example not try secondary DNS if primary is down. The reason why private organizations want you to use their DNS service is because they want to know every site you visit, then sell that information.

This is a perfect line of reasoning, assuming: a) your ISP can competently run a secure DNS service correctly (latency is not the whole story of 'performance') b) it's acting entirely in your interests and not attempting to hijack your DNS service to insert ads etc. Personally, I've had ISPs where neither of these things have been true.

Cloudflare is on record saying they will not sell the information. You can trust that or not but your ISP is almost certainly selling it if it is one of the major US ISP. Verizon owns Oath, Att owns App Nexus, Comcast has a whole suite of adtech companies & owns gigantic publishers. Time Warner literally started out in the sell side of advertising.

  CloudFlare can say anything and have all the good intentions in the world. But, on Android, they are using a third party bug tracking software that they don’t have source control for (Instabug). That third party binary blob requests camera and microphone access.

  I think ISP selling user data is outrageous and should be illegal. Thankfully where I live (EU) I got 20 ISP's to choose from, allowing me to vote with my wallet.

    I don't know much about the ISP market in the EU but Telenor (a Norwegian ISP) owns Tapad which is an adtech company most recently named in a big GDPR case. So its not purely a US based problem.
