Both anime are about the social aspects of playing online games, and feature romance and crossplay. Netoge no Yome is about schoolchildren, but Net-juu is about adults, so take of that what you will.
Both shows are about "supernatural" beings trying to live in human society and the troubles they encounter, which seem to be a metaphor for racism, ableism and other isms. They are similar in tone - heartwarming with some romance and comedy.
Both anime are short shows about meeting a mysterious creature and having adventures with it. Both have unusual sci-fi vibe.
