Chuck and I used OneNote for several years and liked it a lot.
But we switched to Evernote for two reasons.
1. Evernote's syncing is more robust and troublefree than OneNote.
2. OneNote is driving in a direction to become general ""knowledgebase/library/closet"" for anybody, keyed to flexible search. They intend to search on the audio files stored, too.
I finally came to the conclusion that it would be easier to use with customers and collaborators than OneNote. So we switched.
