This is my personal top of the Isekai genre.
Not every existing isekai is in the list, only the one I had readed/watched.
from wikipedia:
"Isekai (Japanese: 異世界, transl. "different world" or "otherworld") is a genre of light novels, manga, anime and video games that revolve around a person from Earth who is transported to and has to survive in another world, such as a fantasy world, virtual world or parallel universe. This plot device allows the audience to learn about the new world at the same pace as the protagonist. Isekai works can also often fall under the fantasy, science fiction, portal fantasy or accidental travel genres."
Some of the titles in this list are not Isekai but very similar to it like "Danmachi(Is It Wrong to Try to Pick Up Girls in a Dungeon?)" and "Suppose a Kid from the Last Dungeon Boonies Moved to a Starter Town".
"Gate" and "Solo leveling" are also revert-isekai.
