Anime can cover more genres than drama and what is shown in anime can't be shown in live action.
My favourite genre is isekai with elves, dwarves, beastman, etc and RPG elements. Is there any live action drama like that? Only one that I know is parody about Yuusha Yoshihiko.
Live action drama is also good and I like both worlds. Imho korean drama is more about emotions, japanese ones are more realistic and crazy. It is good that everything is different, because people can choose what they like to watch according to actual mood.
