This two anime I would say have quite in common. While starting with the obvious that they are both Isekai they also tend to be on the darker side of that genre. Making it intriguing since most anime like them normally starts with a lighter therm. They also have a similar protagonist as it looks at first like they couldn't care a bit about the world they entered and both have questionable values that we as a viewer tend to question our own morality after.
