New Release or Older Books?

Hey guys.

I have a question for everyone. 

Are you more apt to grab a book that's been out for a while? 
Or are you going to run out and grab a new release? 

Jessica has long been a fan of Colleen Hoover and I thought about picking up one of her books.  Why not, right? 

At the same time, I thought it would be fun to throw the question out there.
