Both are laidback comedies and the main character's a witch that adopted some child and became a step mother.
Except the other one has a isekai incarnation and the other one doesn't.
300Slimes has more characters living with the witch and adventuring, the other one is more normal family mothering.
Personally I think that theese 2 belong in the same subgenre of comfy anime.
