The difference is that Kimetsu goes into much darker territory, so the contrast is huge.
So basically, the swing is so huge that it starts to feel out of place.
If I remember correctly, during the drum-demon arc, there was one such scene that felt completely out of place.
They literally saw someone dying a few minutes earlier and started being silly because of something.
In other shows, you'd see the MC getting beaten into a pulp and then all of a sudden help is coming, but that one dude who helps MC is also his rival and starts making fun of him because he is so weak and they start arguing infront of the enemy etc.
It's not even remotely as dramatic as when you have flesh eating demons lurking around that brutally rip you apart for fun.
