The thing is, Flash may be faster than Sonic, but he doesn't have the advantage Sonic does of the rings or the Chaos Emeralds. The rings as stated before can protect him from any hit at least once no matter how strong it may be, and the Chaos Emeralds allow him to transform into Super Sonic. In the Super Sonic state, Sonic is faster, and invincible as long as he has the rings to support it. Just colliding with Hulk at walking speed would be enough to damage him, so imagine Sonic at full speed or using his homing jump. Hulk can get angrier and angrier and stronger and stronger all he wants, but he has to have a breaking point somewhere, and if Sonic can reach that breaking point while he's powered up as Super Sonic, he can take the win.
