Indeed in the eyes of the beholder.  In NYC on Verizon's Fios
9.9.9.9 comes out slightly ahead.

--- 9.9.9.9 ping statistics ---
10 packets transmitted, 10 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 2.363/3.049/3.681/0.392 ms

--- 8.8.8.8 ping statistics ---
10 packets transmitted, 10 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 3.351/3.977/4.755/0.484 ms

I don't use either, instead I query a local unbound which in turn
queries a local authoritative server that has copies of the root
and arpa zones:

stub-zone:
        name: "."
        stub-addr: ...
        stub-first: yes
stub-zone:
        name: "arpa"
        stub-addr: ...
        stub-first: yes
