Classic chess is definitely Magnus, but Hikaru is better at blitz
Hikaru (zero times world blitz champion) is down by some both in blitz & bullet at chess dot com matches against Magnus (seven times world blitz champion).
And of course his percentage is even worse at official FIDE encounters.
But surely enough, Naka talks much faster. 
Magnus. He is just GOAT! Everywhere! Blitz, Classic, 960... Sorry Hikaru, but you are also a great and really nice player.

Hi
Do you like Amogus?
Magnus, since Hikaru is way too loud and annoyingly repeats everything he says.
