Which US news magazine do you prefer: Time or Newsweek?

I've never subscribed to either one; I've just read them in public places where they're available (waiting rooms, cafes, etc.). I like both of them, but I would like to add a subscription to one of them to my recently purchased Kindle. And since I'll soon be paying for a subscription to one of them, I would like your thought on which one you prefer more. Thanks!
