Comedy, horror, or Slice of life, some weird (and sometimes amazing) isekai I watched... Mostly stuff like the Monogatari Series, No Game No life, and Attack on Titan
My favorite types of anime is: Slice of life; psychological horror; drama; mystery. I can't think of my number one favorite one so I just listed all the ones I love.
my favourite type of anime is action, and/or very peculiar anime like Rascal does not dream of a bunny senpai. I used to like the typical isekai or harem though.
Comedy, Romance and the anime having a decent plot/story behind it. (An example would be High School Fleet- every episode got me hooked, along with having a lot of cliffhangers- making you watch the next episode and so on)
