MM is millions of times faster than Godzilla, he could literally sit down and have lunch, read about a dozen books and then take a nap in the time it takes GZ to blink. Skip to around 3:45
Seems like Godzilla's getting pretty blitzed here considering that the death ray had speed comparable to

And it looked so slow at 4:59
However in other aspects MM appears to be at a disadvantage. The building we see Tighten lift is the end part of a rather thin, narrow skyscraper, not a whole one

Tighten can break off and throw part of a skyscraper downwards maybe a few hundred meters but Godzilla could throw a multi-ten thousand ton spider until it was a tiny speck and still going at the peak height of a mountain in the distance

Godzilla's casual beam also moved the kilometer size Mothership sphere and three 700 meter long attachment ships all at the same time, which could unaffectedly contain 9 giant monsters whose combined weight surpasses the 365,000 ton empire state building (Rodan, Anguirus, King Caesar, Kamacuras, Kumonga, Ebirah, Hedorah, Gigan, Zilla).

Godzilla's opponent Monster X could take the force of this beam to the face

Godzilla and Monster X's beams equaled in a beam fight

I haven't seen Megamind in years, but what exactly about metroman's laser vision lets him even hurt Godzilla, beams capable of shoving back Godzilla's own breath all the way to his mouth only left burn marks that disappeared shortly after

Moving your body faster doesn't mean laser attacks move faster too (they could already be fast to begin with) or do more damage per second than they normally do.
