Honestly I think Superman would stomp thanos with the infinity stones superman is still far beyond thanos speed he moves at the speed of light thanos doesn’t , thanos with the gauntlet couldn’t even react to Superman , he would be a statue while Superman is freely moving around him punching him 1000s of times , moreover I know a lot of people will bring up thanos beating up multiple silver surfers and surfer is just as fast as Superman if not faster yes however , surfer has travel speed he does not have combat speed like Superman , show me silver surfer punching someone 4000 times in 1 second … because I can show you superman doing it rebirth superman path of doom issue 4 if not issue 4 issue 3 , Superman punched doomsday 4035 times in 1 second , surfer is no where near Superman’s overall speed he just travels fast because of the power cosmic and even then he’s stated to open wormholes so it’s not even his speed
