Which is better: Disney Dream or Allure of the Seas?

I am planning a cruise for my 17th birthday next year (since I am a guy and not my sister who is a big party thrower) for my friend, my father and myself. We are all Disney fans and love the theme parks and I went on the Disney Magic a couple times when I was younger, and I also went on the Explorer and the Enchantment of the Seas. I love them both, but dont know which to choose. Both look amazing, high tech, suitable for both an adult and teens, and gorgeous, but I am still unsure of what to choose. Both of the prices are the same on the rooms I was looking at but other than that I am just so unsure. PLEASE HELP!!!
