Each has its own points. You need to watch both at times.
Drama is a must for romance with all its variation. Also for family moments and stuffs.
Anime is for fantasy and action. Although good anime= manga so its basically manga that I care about.
In terms of pure quality, anime(manga) is way better than drama. There are many classic and unique anime(manga) that can be considered as world class level. But I cant tell about even 1 drama(japan, korea, etc.) that is really good like Game Of Throne or Inception level.
As someone said, there's a drama called tribes and empires airing right now that's trying to be like Game Of Thrones, and is actually pretty good from what I can tell.
Inception is a masterpiece scifi, that's something that essentially does not exist in drama. It's like scifi just not an asian thing, the few scifi dramas that do exist have really bad "science". So if you're looking to compare anything to Inception, then there's just no competition, but asian drama has other things to offer.
Nirvana In Fire is at least as good as Game of Thrones in my opinion, and does feel a bit similar too. Keep in mind people have different tastes, Game Of Thrones is one of those series that I thought was really good, but just simply could not get into.
You should really check out chinese drama before quickly concluding that anime has more masterpieces than anime, chinese drama didn't always use to be really good but recently there have been what most would consider masterpieces: Nirvana In Fire, Battle of Changsha.
Fans who only watch korean dramas will mention shows like Signal, which I think is good but overrated, and not a masterpiece. Then there's shows like goblin which barely has any substance to call a masterpiece. Maybe Reply 1988.
From Japan, there's probably 1 litre of tears and Tenno no Ryoriban.
I find it hard to believe you've found no "world class"/masterpiece drama. Have you seen a lot?
Of course, I can also name many anime/manga I believe are just as good as Game Of Thrones, so this isn't saying drama is better. if you see my earlier post, you'll know I actually believe the best anime is better than the best drama. That opinion is slowly fading though.
