Hey guys! I am looking to buy a Box set of the first 3 books in the mistborn series I saw there are 2 publishers: Tor teen and Orion(less colorful on the outside), what is the difference between them? Which should I buy? I guess it doesn't really matter but as I am ordering the books online and can't see their inside, I thought I would ask to make sure there isn't a big difference. Thanks!
