Quicksilver, as his name implies, is really fast. His speed has been estimated well over 8500 miles per hour. To put that into perspective, even the fastest car in the world is only capable of achieving speeds of 301 miles per hour. Simple math says that Quicksilver is 28 times faster than the fastest car in the world.
Wally West is the Fastest Flash and is arguably the fastest being that has ever existed, as said by Max Mercury—and it has been remarked that Wally and Barry are the only two speedsters that were fast enough to even outrun death itself.
In almost every measurable way, the Flash is exponentially faster than Quicksilver.
In a competition of speed between the Blue Blur and the Scarlet Speedster, it will take more than math and science to really comprehend their overall speed. However, taking all things we know into account, Flash would win a typical race against Sonic the Hedgehog and come out as the faster of the two.
Fans often wonder who is faster, Sonic or Flash. Whether it's Barry Allen or Wally West, The Flash is the fastest speedster in the DC universe. Of course, Sonic the Hedgehog is the fastest being in his video game universe and he would make other speedsters jealous.
Hyper Sonic has an incredible strength that no one could ever imagine. Hyper Sonic's speed is faster compared to the previously mentioned speeds. Believe it or not, he can reach the speed of light, about 671,000,000 mph.
Like other speedsters, Godspeed can run up to 10 times the speed of light by entering the Speed Force.
While Quicksilver is often thought of as the fastest of the Avengers, one hero fans know from the movies can actually outrace him when they need to. Many heroes possess enhanced speed, but Pietro Maximoff is generally considered Earth's fastest man (at least in Marvel Continuity).
Quicksilver, Marvel's Answer to The Flash
Quicksilver has actually had two adaptations in superhero movies, once by Evan Peters in Fox's X-Men: Days of Future Past (2014), where he had that iconic kitchen scene that really showcased his speed, as everything was slowed around him.
In a direct physical speed matchup, The Flash will definitely trounce Thor.
Despite all evidence to the contrary, Superman soundly defeated Thor when the two heroes actually fought. Their most meaningful interaction came when the Marvel and DC Universes collided in Kurt Busiek and George Perez's JLA/Avengers in 2003.
Shazam can fly at the speed of light, which makes him faster than almost any other hero, but both Barry Allen and Wally West are able to move at speeds faster than light, meaning that while they would have to push themselves, at least two Flashes are faster than Shazam.
As noted, Flash is known as the fastest man alive. As such, it isn't a good idea to challenge him to a race. Aquaman is also fast, but he's nowhere as fast as Flash, not by a long shot.
Superhuman Speed: The Black Flash can move at vast superhuman speeds, easily keeping up with Barry Allen, and surpassing the speed of light.
Despite being surrounded by Thor, Iron Man, and Wanda, Black Widow is one of the most valuable members of the Avengers team. In one of the recent Marvel issues, Natasha Romanoff has proved that she can easily beat The Flash from DC.
The Flash's Speed Would Overwhelm The Wall-Crawler
The Flash is so fast, he's run through time, vibrated through walls, and can throw a punch with infinite mass behind it. The fight might be close, but Spider-Man would have a difficult time slowing down the Flash enough to beat him.
Thor has access to the Bifrost, which would allow him to travel to all Nine Realms beyond the speed of light. Although Captain Marvel is fast, the character still has to move across universes, which gives Thor the obvious advantage.
As Flash runs after his target, he reflects on how fast he is, especially compared to Superman. Barry confirms that on the ground, he is indeed faster than Clark because Flash can do things Superman is unable to do, such as being able to vibrate his molecules and phase through solid objects.
The 2 main modern Flashes, Barry Allen and Wally West are both capable of running faster than light.
In the DC comics, Accelerated Man is the Earth 19 equivalent of the Flash. It is unknown whether Accelerated Man and the Flash of his Earth have any relation in the Arrowverse.

Silver possesses the power of telekinesis, allowing him to move objects with his mind. While he may not be as fast as Sonic, he can levitate himself and fly around with ease. He specializes in a long-range fighting style, being able to hurl heavy objects at his enemies and block attacks by creating a light barrier.
According to the producer of Sonic Forces, Shun Nakamura, Infinite was created with an impressive and strong presence in mind since he would be accompanied by old bosses in Sonic Forces. This is the reason why he was made stronger and faster than Sonic the Hedgehog.
Assuming Sonic is about the weight of a small man, he'll accelerate at about 64 meters per second squared, which generates a force of about 4,480 Newtons. A bullet, in comparison, flies at an average speed of 1,700 miles per hour.
