It has really good pen/stylus support. It has completely replaced handwritten notes for me.
However, although it's amazing compared to a pen and paper it's still incredibly frustrating to work with.
* It can't handle large amounts of handwriting without igniting relatively powerful computers
* It crashes constantly when trying to balance pen input with palm rejection
* Syncing doesn't really work with non-trivial merging and doesn't handle sync errors nor errors in general well -- all of these usually end up with handwriting layered on top of itself
* Syncing is basically out of your control, you can't do partial syncs when you really need a section/page fast, and large notebooks with handwriting can take hours to sync completely. I've basically resigned to splitting my notes into many smaller notebooks.
* Handwriting on the "Desktop" version is a complete joke and so you're constantly switching between the that and the app to get good handwriting and more features.
So it's great, until it doesn't work then it's a nightmare.
OneNote works fairly well on Windows. The main issue I have with it is usability.
Performance on Macs and iOS is fairly terrible though, from syncing lag, to input lag, (on an iPhone 6) to long load times.
