2 years later, and I found this thread because of being dissatisfied with Evernote's handwriting support, and looking for other opinions.
I do believe that E. is still WAY inferior than OneNote in this regard. Just recently, I attended a presentation. With OneNote on my iPad and the Pencil, I could:
take written notes (of course)
take pictures of slides, instantly resize and mark them, write notes next or under or over them, or wherever else I wanted
move ANY item (text, handwritten or typed, images, drawings) and put them anywhere else
and all in one long consecutive thread. No need for opening new pages, no need for working in another app etc.
All in all, OneNote works like a physical notebook, where you can write or draw what you want, where you want. With benefits of picture making, easy erasing of large items, moving items around etc. Really great.
Later on, I tried to simulate this at home, with Evernote, on my iPad. It absoultely drove me crazy. It doesn't even come close to the ease of use and convenience of OneNote.
I think it's long overdue for E. to improve in this field. Handwriting on computers and tablets is not going away, and is not descending.
