OneNote allows you to arrange text freely on the digital paper mimicking the way it would be done with a real pen on real paper.
Pro Comprehensive organization methods
Can have multiple 'tabs' at the top like in a web browser with many notes within each 'tab'.
Pro Stylus and digitizer pen support

OneNote will alert you when a chance in made on your shared note.
Pro Integrates with other Microsoft services
Integrates well with Outlook, Office, and OneDrive.
Pro Powerful table editor
Adding and resizing rows and columns is easy and flexible. This makes for an easy way to adjust a note as it grows in content size.
Pro Supports hierarchical organization of information / notes
OneNote is designed to allow hierarchical organization of information. This is achieved with grouping into the following categories and UI elements (Notebooks, Sections, and Pages). Both Sections and Pages allow additional groupings that can be expanded / collapsed in list view.
This can be incredibly helpful for quickly taking notes and organizing them for work or personal projects.
For example, you could have a Notebook for "Cooking Recipes", with sections for "breakfast, dinner, desserts", where individual recipes would be page entries (i.e. the "Desserts" section would have pages for brownies, chocolate cheesecake etc).
Pro All indented lines under the first can be expanded and hidden
Which makes it easy to quickly look at the high level of notes, and then drill deep into each point.
Pro Insert files into your notes
You can add a variety of different files into your notes including images, video, audio, and more.
Pro Strong search features let you quickly find what you're looking for
If you don't want to search through all of your notes, you can narrow it down by specifying the page, section, group, or notebook.
You're not limited to just searching through your text either. You can search for text in images, video recordings, and audio (this is off by default).
Pro Very similar design for those used to Microsoft programs
If you have experience with other Microsoft programs such as Microsoft Office, you'll feel right at home with the design of OneNote thanks to the similarity of the menus.
Pro Offers flexible encryption
Unlike most other apps, you can selectively password protect, and fully encrypt, individual documents or entire folders. This is especially important to many people with data stored in the cloud. As of early this year, even the free version supports encryption. Microsoft has also enhanced their internal security methods for storing data on OneDrive (where OneNote performs sync), which makes it more secure than most of their competitors (including Evernote).
Pro Converts handwriting to text on Windows version
You can take handwritten notes on your mobile device with a stylus or digital pen and then convert the handwriting to text later on your Windows PC.

The app has 5 different views - schedule, day, 3-day, week and month.
Day, 3-day and week views split up the days horizontally and hours vertically. Month view lays out all days in a grid and displays up to 3 events in a day.
Schedule view displays an agenda view that allows browsing all events by swiping vertically. Additionally, the way events are displayed in the agenda view is context-aware. For example, adding an event called "gym" will display the event on a background with a dumbbell.
All views except for month view can be split horizontally to display a condensed month view at the top that can be navigated by swiping horizontally.
Events can be added from any view by clicking the red plus button that's available at the bottom-right corner of the screen.

Pro Advanced functionality available through IFTTT
IFTTT offers over 198 channels to plug into the users Google Calendar.
Con Not available for Linux
There is no native Linux client for OneNote available, and most likely will never be created. Users can use the web based client, but a native app would be a better choice for those that use the app frequently.
Con Text editing is weird (poor UX)
When clicking in the middle of a note, it adds something like a text-box positioned in the middle. If you move that field to the bottom right, it gets weirder. You can end-up with an empty note, having an empty text-box 1km to the bottom-right of it.
Con Syncing issues
It tells you there are conflicts between a note on the PC and on the Android because of the timing of the synchronization but doesn't try to resolve itself.
Con Requires a Microsoft account
You need to have a Microsoft email to sign up for OneNote (Outlook, Hotmail, or Windows Live).
Con Not open-source
This application is proprietary, and thus cannot be modified or freely distributed.
Con Platform dependent
The newer versions for Windows and Mac are converging, using the Windows style layout (with a more more consistent and usable UI).
The original OneNote for Mac for example is very different from OneNote for Windows. Because Microsoft has a vested interest in making sure the Windows version is superior, the Mac version tends to lag behind in terms of functionality. Tutorials and other forms of documentation available online generally apply only to the Windows version, which implies non-Windows versions are undocumented.
Even worse, because the documentation rarely, if ever, indicates it only applies to Windows, it's easy to waste hours trying to make non-existent features work. As such, the documentation is "negative documentation" (i.e. worse than no documentation at all).
Con Sync isn't stable
Many users have reported synchronization issues. While not everyone will experience this, it can be difficult to troubleshoot, with some fixes resorting to editing registry keys in Windows when using the Windows client.
Con Uninspired, bland user interface
Many of OneNote's competitors use Material Design and bold colors to create a minimal, clean looking interface.
OneNote has a bit more of an outdated look and can feel over crowded at times.
Con No backup on Windows 10 free version
If you accidentally delete a section on the windows 10 free version of Onenote, there is no backup to fall back on.
Con Menu/ribbon can feel crammed
OneNote offers a lot of formatting options, which results in a lot of options being crammed into the ribbon. It can feel somewhat cluttered and takes a bit of time to get used to.
Con Doesn't automatically sort (by name, size, date)
You can't choose to sort automatically. Just do it manually.
Con Some feature require external apps
Sort Pages, find and replace, etc need external apps called onestatics.
Con The added flexibility means your notes may feel cluttered
Since you can place elements anywhere you'd like on your note, you have to pay attention to how you structure it. For some this added flexibility is a huge selling point, but for others it could become distracting and makes notes feel difficult to digest.
Con You cannot use local OneNote files with the version of OneNote that is included with Windows
There is a difference between the OneNote that is included with Windows 10 and the OneNote that comes with Microsoft Office. The version included with Windows cannot use local OneNote files and requires you to be online to access your notes.
See here for this and other differences.
Con Search function is lacking advanced features
e.g. Searching for "friend" will find "friendship" and "friendly" (because "friend" is at the beginning of the word); using this query will not find words such as "girlfriend" or "boyfriend."
Con Google tasks do not show on Google Calendar
You can create tasks in your desktop Google Calendar but they will not sync nor show up in your android Google Calendar
Con No weather forecast
The Android app version of Google Calendar does not show any weather forcast information, even if it is added as an extra calendar in the web application. Being that weather is tied into Google Now, the absence is surprising.
Con Month view shows limited information about the event
Month view does not show how many events there are in each given day or color-code them in any way, only informs of their existence.
Con Privacy concerns
Google integrate all their services to connect and mine information on an individual to better profile and target advertising.
Con Some recurrence options not available
If you want to add a recurring event based on quirky (but normal) calendar rules, it's not supported by Google Calendar. For example, if you set up a financial calendar in Google Calendar and an event falls on a weekend or bank holiday, Google Calendar cannot schedule the occurrence properly. Worse yet, if you submit those calendar occurences via VEVENT details, Google Calendar displays different information if you use the mobile calendar vs. the desktop web calendar.
Con Once you create a event on a Calendar, you can't move to a different Calendar
Con No vertical scroll
Like iOS and outlook for Android.
Con Horizontal Scroll
Does not vertically scroll like ios calendars on outlook calendar.
Con Slow syncing of external calendars
Google Calendar is known to sync external calendars very slowly, takes hours if not a full day before the updated events are reflected.
Con No natural language input support
The Android app has no natural language input support, while it's available using the web client and in a limited capacity using Google Now.
Con Weak default view
Even if month is set as default view, as soon as you touch a day or an event, you have to carefully select twice to get back to month view.
Con Time zone is incorrect no matter what's done
Con Timezone for Moscow is incorrect
Timezone for Moscow is 1 hour off. This makes the calendar unusable in Russia.
Con Setting up non-Google calendars requires accessing web client
There is no ability in the Android app to access other calendars. This limits the usefulness for people that use more than one calendar, such as OSX and iOS users.
