Manga, Manhwa or webtoon?

Nowadays I find it hard to read japanese mangas because of the artstyle. Webtoons is more versatile in terms of plot and art. Ofc there're some exceptions. I did try to look for japanese mangas but rarely find anything good.
Manhwa (from Chinese mangaka) 's artstyles is good but most of them is a bit too flat. Sometimes the plot makes no sense for me.
So what's your favorites?
