Head to Head: Drafts vs. iA Writer

Word processing for iOS is a bountiful well of possibilities with a lot of variety. During the day when you're out and about, it's easy to pull out your iPhone or iPad Mini to do a little bit of creative and productive writing during those small pockets of time. Many apps are thrown out there in this department like Evernote, Byword, My Writing Spot, Write 2 or Apples own Pages. While these are all valid options, I find that the best of the bunch that are the most effective is Drafts and iA Writer. But the real question is which one deserves your hard earned money more?
