Superman still kicks his a$$.....savage hulk can be knocked out quickly by superman.....that was always what the thing was shooting for was to end it quick but he didnt have the strength (excluding spikey version)....superman easily knocked hulk out....savage or not he can be knocked the fu$& out!
Flash's speedforce aura protects him - it probably makes him even more invulnerable than the Hulk.
Not to mention the fact that the Flash's healing factor works faster than the Hulk's, even if it doesn't work to the same extent.
If he has the durability of EITHER character, he'll be fine.
If he has the durability of the average human, then he would die at the kinds of speeds the flash travels at, and would break every bone in his body if he punched with the force the Hulk can punch with.
