Wally West is the Fastest Flash. He has been confirmed to be the fastest being in the entire DC Multiverse. While most to all speedsters can make a connection and draw upon this force, Wally "mainlines" power from the Speed Force itself and cannot be cut off from the source.

Short Answer: Godspeed is faster at the current time. Well, technically the Flash is the fastest because he's the protagonist and he also is the source of the speed force, Barry Allen. But at this time Godspeed is quite a bit faster than Barry.

What is The Flash's top speed?
It is said that The Flash can run 13 trillion times faster than the speed of light, which would mean that he can travel up to 1,750,000,000,000,000,000 miles per second. The Flash gets his incredible speed and abilities from The Speed Force.
Garrick became one of the elder statesmen of the DC Universe, a member of the Justice Society, and an all around role model. His years of experience made him a great hero, but speed wise, Jay is the slowest Flash.
