Switched from Evernote to OneNote a long time back, and am enjoying my decision every time I use OneNote.
I like the whole idea of being able to write anywhere and everywhere in the page and move the notes around. Usually, I log high-level ideas in a page to discuss with colleagues and during the meeting add comments/feedback from different people. The interface makes this very easy and intuitive. I add a lot of PDFs (of graphs, diagrams) to my notes, and the rendering of these (when inserted as printout) on a web page (that I can share with coworkers) is flawless!
Update: Ability to share a specific page of a notebook is still missing. It would also be awesome to be able to customize the formatting styles (for instance, change the font for the `code` style) in Mac.
