I doubt the sub-standard CN/KR popcorn I consume on a daily basis can compare to almost any decent, properly edited and professionally published English novel regardless. The themes themselves are a problem, too, due to me only being passingly familiar with Oriental culture due to the dedicated auti- I mean efforts of beautiful translator/editors and their notes. So I'm likely missing a giant chunk of awareness about the cultural and historical themes, and that missing chunk makes it practically impossible for me to judge a book on its actual merit. So I honestly just lack the knowledge and skills to adequately judge! Not even mentioning all the wordplay and literacy wizardry that gets lost in translation.
As it stands, I'm not really that excited when someone mentions something from the however many kindgoms era or whatever with lubu and all the other shite I never remember, but if you mention something similar to King Arthur I get that little recognition tingle. I can pretty honestly state I haven't read any of the Chinese classics and I have no real interest in them, so to me, western fantasy will always be preferable.
