HP Verse wins.
By this time, Quicksilver has lived with his abilities for at least 19 years. He's grown up in a perpetual hell of slow-moving incoherence. With thoughts and movement moving at nearly the speed of sound, his hellish existence of living miliseconds as hours as slowly rotted his brain. It's evident in his white hair and pale ghostly features.
Unable to live in this world of un-moving, Pietro Maximoff decides to end his worthless existence by running fullspeed into a rock-wall on the edge of the woods near his home. Exploding in a misty spray of blood and viscera.
Flawless victory.
QS could probably take out most of them, but if even one of the decent spellcasters gets of a some kind of omnidirectional-blast he could be instantly shut down, Like when Hermione stopped the pixies in the 2nd movie.
Also Voldermort and Snape have both shown mind control abilities int he movies (and can turn to smoke / fly)

All that would due is freeze any nearby wizards.
Didn't freeze any wizards when used on Pixies, just need the right spell.
only chance the Wizards have here is if their numbers can distract QS enough for someone like Dumbledore to get his thoughts together, possibly by mind-controlling QS.
