I host my own with Pihole and Unbound (which I would recommend if you have the technical expertise). Adguard gives you similar functionality on a hosted service (ie. you don't have to set it up yourself).

In terms of which public servers are good, or at least censorship free, I just checked Google, Cloudflare, and Quad9 and they all resolved RT and Sputnik, sites censored by the EU. I'm located in the EU.
