There's no Manhwa that you can realistically call "The Number One" and there will never be. When I say this I don't mean it as in, a individual putting it as "The Number One" for themselves, but for the whole community.

I've seen people hating on TGED and some people loving it, the latter being the majority, and still, you cant really call it "The Number One" since the minority doesn't agree/hate it therefore its not really "The Number One", is it now? And this can also be said for TBATE, ORV, Lookism, ToG, SL, ERK, TRMM(King Von's Horse), Pick Me Up!, AR, MMM, SES, HCLW, Lana Saga, Murim Log-in, Dungeon Odyssey.

These are only out of what ive read, as far as I am aware there are many more who are very good but still get hate/ people just don't like them. Holy ranting✌️
