I re-evaluated my DNS provider choice a couple days ago (good timing, apparently, as I was using Google before then). Switched back to OpenDNS because their servers responded faster than Google's, and they no longer do the ad/search page redirection thing, as of June 6 2014.

I used GRC's DNS benchmark tool to discover this. Also the particular OpenDNS servers which responded faster were different from the two that they tell you to use, so the fast response is probably helped by low load (fewer people using these undocumented servers). Going from memory because I'm at work, I think they ended in 202.222 and 222.202 and 202.123, whereas the officially listed ones end in 222.222 and 220.220.
