Well...Superman fighting ANYONE depends on a number of factors. Whether the writers of the fight are being fair and unbiased (*cough* Screwattack *cough*) and what version of Superman you're referring to. In my opinion, the Superman that fights Goku has to be cannon, which would be Post-Crisis and New 52. Pre Crisis is basically the equivalent to GT Goku and All Star is like Goku from the movies. Secondly, you'd have to have a pretty good understanding about how Ki works in the Dragon Ball universe, as it is essentially energy in general, seeing as how when one makes a Spirit Bomb energy from all around the Universe is used for it.

As for Saitama, it would also depend on the strength of the monsters h'es been facing. Sure he's been taking them all out in One Punch, but so far he's only shown feats comparable to that of Krillin, Tien, or even Uub from Dragon Ball. Until he starts KO'ing planet busters, then we could talk about him going up against Superman.
