Spiritually Speaking Why do people like HP More than Twilight?

Ive been a Twilight fan for a looooooooong time. The other day i was reading harry potter and the character of Sirius black turned into a wear wolf/dog thing! They totally ripped off twilight because Jacob and his friends were werewolf FIRST!!!!! Also the stupid writer of Harry Potter didn't even try to change the last name! Both of the people are WEREWOLFS AND HAVE THE LAST NAME OF BLACK?!?!?!?!?! Why do people like harry potter more? its an obvious ripoff of twilight
