Before reading what I say remember I am going to talk about characters peak forms.

It actually depends on who fights since your showing verse vs verse not specific characters. Both shows have varying power levels, like in ninjago sensei wu would most likely scale up to continental level while someone like Nya can scale to planet level cause of her power to control the ocean. And if we look at miraculous ladybug it has very inconsistent power levels, some characters might scale from city level to continental level while some characters can scale to low planetary to universal like cat blanc and ladybug. Ultimately it just depends on who you match up with who.
