Don't try to climb Opm or Dbs, you don't know how to climb either. For a simple summary, a being without limits (saitama) vs a limited being (goku). It's not difficult to choose the winner.
If we take the entire universe of OPM and Dragon Ball and disregard Saitama, DBS has a much larger scale, with characters even stronger than Goku.
The power scale in OPM doesn't increase when Saitama showcases his feats, but rather when other characters do, and that's exactly what happened in the recent chapter.
Void, a guy who isn't Saitama, simply folded/held the fabric of space-time with his hand, and we know for sure that Saitama defeats this guy easily; Saitama had already shown the ability to easily handle dimensional portals and get them.
OPM works on the scale of infinite universes, while DBS is limited to a few universes.God is from a higher dimension where concepts of size and distance are irrelevant. Again, look at the level OPM has reached; Saitama already surpasses Goku, and the end of OPM will not only make DBS seem like child's play in comparison but also other mangas with scales greater than DBS.
Man, Saitama beat Garou who was better than Goku in martial arts by 1000000000x.
Seriously, it's hilarious to see Dragon Ball fans who don't understand anything about scale trying to debate and scale verses.
Zenkai is over bro, Goku literally declares this in the manga pages, he literally said he has LIMITS, lol the complete opposite of Saitama.
The management and increase of energy was the key to their victory and Goku's increase in power, they need to resort to strength enhancers etc... In short, limited weaklings.
