Can anyone recommend a modern alternative to "namebench"?

That's an old Google Summer of Code project that determines the best-responding DNS servers for any particular installation. Python 2 based, so it doesn't even run without mods on a modern Ubuntu system which defaults to Python 3. Also, it hasn't been updated since 2010 and certainly some of the more-popular public DNS servers have changed since then. What techniques or apps are used now to do this?
