when it comes to us or chinese comics, basically nothing. i enjoyed those old AVP comics from darhorse and that about it as far as us comics go (did read some less serious shit like gen 13, witchblade & darkness for as long as they remained decent/fun, also remember liking golddigger as a child, but none of these are really great and the good ones only remained good for so long. i dont think good chinese comics even exist, i know only one and that was called CAT or CATS (main chick is a lil bit like cammy and style and choreography seem like hiroaki samura aka blde of the immrtal artist.
compare this to mangas where there are literally dozens of great mangas and even more good ones. great ones like blade of the immortal, akira, slamdunk, vagabondfirst half of berserk and many more titles i cant remember cause i dont even like mangas in general anymore, meaning theres more i left out. saddest part is the difference in quality betweeen these and ch/us comics is huge. its like comparing godfather to something like icarly on nick.
also i love kof, kof, ss, ds, sf & ff are filled with potential greatness if turned into something readable or into an animation, but it has to be handled with care. even boti on of the best mangas ever made had an anime that sucked balls. same applies to kof comics. i can only imagine how good it could have been if the person making it was great himself.
