I have a slightly more positive view of manga because it's more likely to be hand drawn (March Comes in Like a Lion, Made in Abyss) but one of the things I really don't like about manwha/manhua is that it's always (as far as I've seen) a continuous strip which means I have to scroll a lot. I have an auto-scroll extension but it makes me dizzy after a while. I do appreciate how each of them have their own unique style, I think that's pretty cool.
Also my first "manga" was Scott Pilgrim. Author's Canadian and IIRC it was read right to left but everyone still called it a manga.
Well that's good to know.
