Say what you will about Harry Potter, but that series rekindled reading and made it a global craze.
While you could argue whether or not HP is actually good, the issue with Twilight is that the relationship it portrays is sort of fucked. HP doesn't have *THAT* issue.
I'd argue Harry Potter is a much more cohesive work, to say the least, in comparison to Twilight as well.
Harry Potter at least tries to tell one hell of a tale of relationships (past and present), histories, magical being and artifacts, and its all jumbled in teenage jinx's and adventure.
Twilight is simply illogical, and made up of magical problems, poorly re-imagined horror-types (vamps and wolfies), and ridiculously fictitious deus ex machinas to save the day. Quite frankly, some of it is just embarrassing.

EDIT: As much as I like the occasional read on CRACKED, their articles talk out of their asses sometimes. And yeah, I don't think a minotaur rape scene was to be implied given the target audience. Some authors are fucked up, but I'm giving Rowling the benefit of the doubt... if any... other than in CRACKED's head.
