I'd say "comic" is a better translation, since the term BD encompass both self-contained stories (like Poyangang) and album series like Tintin, and newspaper strips. You wouldn't call Asterix a graphic novel. The term Graphic Novel was invented in the US initially to describe comic books which contained a single self-contained story - as opposed to newspaper comic strips and superhero periodicals with never-ending storylines. So it is a subset of comics, which are marketed differently.
