Throwing my hat into this thread, I believe Flash much is faster than Sonic the Hedgehog.

Now I dunno everything about the Flash, but I know he is perhaps the second fastest character in the DC universe. What brings up my reasoning why Flash is faster than Sonic is because of the speed-force. 53OyPYa7SEI In fact, Flash is so fast that those in touch with the speed force have a unique Grim Reaper to collect their souls.

Sonic is indeed fast, but if gameplay truely shows how fast he is then Sonic, such as in Sonic Unleashed, how fast it takes for him to travel through stages and advance to the next location is no where near close to the Flash.

However while Sonic himself isn't as fast as Sonic, I believe AoSTH Sonic with the Ring of Ultimate Velocity is fast enough to outmatch Flash. Before obtaining the ring, it is shown in Mass Transit Trouble that Sonic is able to run to three furthest points on Mobius to stop bombs syncronised to blow up, however this exhausted him out. when he unlocked the power of that ring in Sonic Christmas Blast, it shows Sonic was now able to run freely around mobius in many laps as he wishes without taxing his stamina.

So from all the known versions of Sonic, I believe AoSTH Sonic with the Ring of Ultimate Velocity is the fastest.
