Very badass, both moments
Yeah, he called Quicksliver slow and has been described as being as fast as lightning.
Personally I never cared for super speed, tanks shouldn't need super speed anyway it makes them seem less tank-y.
I never cared for Thor having super speed, great fighting skills, super strength, weather control, nigh invulnerability, weapon mastery, superhuman reflexes, inter-dimensional travel and over a thousand years of battle experience is what I care for.
With Stormbreaker MCU Thor now able to travel through space and in between dimensions, so suck it super speed.
And if we're to belief that it was a leap that took Thor from the throne room to the bBfrost at the end of Ragnarok, that's a MUCH bigger super leap than anything MCU Hulk has ever done.
