If you like ecchi, the genre actually has seen a renaissance thanks to isekai mangas and are able to get away with much worse stuff nowadays compared to before, but in anime it's the opposite since they get censored to hell and back.
For guilty pleasures, Reincarnation Coliseum is the one I'm liking the most alongside Isekai Koushoku Musou Roku.
For normal stuff, Isekai Apocalypse MYNOGHRA, an isekai to a world that's suspiciously familiar to players of Heroes of Might and Magic, some nice war tactics and politics.
I'm always curious about these sound differences, that's something I only knew even existed after this era was already over.
