I prefer Isekai's and Reincarnation types because more or less you know what you can expect and it won't take like 100 or more chapters before we can see the MC become powerful. My preference is Fantasy, Sci-Fi, Supernatural, and Romance x Comedy. I don't read Yaoi or Yuri tagged ones. I will read Gender Bender(Guy turned into a Girl) as long as there is no romance towards the MC.
