Very similar humor and mood. Lots of characters with completely different ideas of how situations should be handled. They are both some of the rare anime that make you actually laugh the majority of the time watching. I can imagine Oyasumi as an arc in Gintama and it would work completely fine.
I'm suprised to see that no one recomended Gintama as a similar anime. Gintama and Maoujou share a similar type of nosense humor that makes me cry from laughing almost every episode. As far as i remember these two and nichijou were the only ones that had me laugh so loud.
