Evernote vs OneNote: Discuss?

So I'm seeing today that Evernote is getting an update on WP8 which leads me to the natural question: if I am a heavy OneNote user on desktop and WP8, is there a compelling reason (or reasons) to make the switch? I use OneNote to organize everything from projects at work to keeping my tax information together, so to say that I have a lot of my life in it is pretty on point. And I can't say that there are things I wish I could do, but that might just be ignorance of the power of Evernote. I realize that I could start playing around with Evernote on my own, but I figured it would be much faster and frankly more informative to ask the question here. Thanks!
