I assume this is for a Tor relay?

If you plan to run an exit relay, you should avoid third party
resolvers.  Google currently gets to see ~35% of all DNS requests coming
out of the Tor network.  We shouldn't hand any organisation such data on
a silver plate.

If you don't want to use your ISP's resolver, I recommend setting up
your own, local DNS resolver such as unbound.  Recent versions of
unbound implement qname minimisation, which is a great feature for exit
relays as it minimises the exposure to some network-level adversaries.

Quoting Peter's quick guide [1] on setting up unbound:
