Big differences, especially since the last evernote update, on android at least. Camscanner produces better images. Cleaner and sharper. In the last update evernote has turned the image compression up to a ridiculous extent. An 8M image of a handwritten a4 page is compressed to a 50k jpeg, which has horrible compression artefacts. Really stupid decision - can't understand why there aren't more complaints. But camscanner produces pdfs so you actually have to open them to read your note. Also for handwritten notes, evernote ocr works much better. These two are show stoppers for me, so I have to put up with evernote.
