Scrivener or OneNote

Are you contemplating whether to purchase Scrivener to plan and write your novel on Windows? You may already have OneNote on your computer. So which should you use, Scrivener or OneNote? I tried Scrivener again last night. I couldn't even make it through the tutorial before I was confused beyond words. I hear there are some neat features on it, but I'm going to stick with OneNote and Word.

Believe me, it's hard to say that since I'm normally not a Microsoft fan. Am I the only one who isn't impressed with Scrivener? I just might not be smart enough for Scrivener.

Edited: I've been revisiting Scrivener and may be changing my mind as I get more comfortable with it.
