Goku has kept up with Jiren who was able to move during Hit's Time Skip and broke through his Cage of Time. Hit's Time-Skip takes time to where there is none and stores it to create a parallel universe. Jiren was able to move where no time was present and he broke through such an attack with mere movements, which is a feat of Inaccessible speed, making Goku fast enough to keep up with Post Crisis Superman.

Add in the fact that Goku is far, far more skilled and you've got yourself a win for Goku.
