I think you guys are overthinking this.
No, Saitama doesn't deserve the power he has but he's a comical character who is not meant to and will not lose as that's part of his character and the anime/manga.
It's meant to be funny, and he literally cannot lose as that's set in stone by the writer.
Goku, on the other hand, is more badass. He has had character development which we've seen, although as we've seen his character develop, we've also seen him lose. DBZ is comparatively a serious and realistic anime meaning Goku has the ability to lose. This is a trait Saitama lacks meaning Saitama would win any day.
Though, on a side note; just because someone makes a video on something does not automatically mean they're correct about the argument.
