Manga and Japanese Animation or American Comics and cartoons?

I'll go for anime and manga because in both cases manga and anime have way better drawings that all of those DC comics, Marvel and Cartoons (note i'm not saying american drawing, at least for cartoons, is bad). Also the plot in anime/manga is superior it has way more depth and in most cases you get emotionally attached to the main character (at least in most manga/animes that I read/watch). Plus manga and anime generally require a bit of thought you have to analyze what's going on but with american comics and cartoons it's pretty straight forward so it get pretty dull after a while. Plus if you had anime/manga characters fight the american comic and cartoon characters anime and manga would kick major *** (just Goku can beat them all with his finger.) So what's better?
