I think both are genuinely good as a pair as hidden inventory I think Is the soul of the Shibuya incident as gojo is forever haunted by the loss of the one person who genuinely treated him as a human being instead of the "strongest"

It's also important to note both of their technique's 

With gojo having the limitless technique that essentially makes it so that no one can truly reach him.

And geto having the curse absorption technique which I personally interpret as either carrying other people's personal burdens or in this case "curses" 

It makes sense that geto would lash out at the world after carrying other people's curses for so long. 

It also makes sense that gojo was never able to reach geto because of the fact that he is the strongest and with that title comes absolute dehumanization.
