Yeah, I don't see why people have to choose. I'm a fan of both. Harry Potter is written brilliantly stylistically...and of course every other way, J.K. Rowling is just a brilliant writer. The thing with Twilight is, it's written in such a way that you wanna know whats going to happen. It's not so much the writing, but the actual story. The plot is what gets you. Both are also good for people who like to visualize when they read. Stephenie and J.K. are both very detailed.
And yes, I love the books so much I can't hate the movie even if it does suck haha
