After the debate I had with @gearsecond659, I feel humbled. Even though Bellcross doesn't have "nanosecond speedblitzes" in the traditional sense, he still reacts at FTL speed, because he is constantly fighting at FTL speed. You can call it "combat speed".
When I look at Thor's fight with Gorr, it is much the same way as Bellcross. The two are literally fighting at FTL speed, zipping across the cosmos and smacking each other light-years away. Anyone with street level reaction time wouldn't be able to see a single thing, and wouldn't even notice that a moon bigger than Uranus has a crack in it ("that's no empty moon") let alone stop on a dime and react to it mid flight.
This was a Thor unleashed, and I've never seen anything like that from Wonder Woman or Superman, only the Flash.
