Pros
Pro Unlimited and seamless sync across all Google connected devices, from mobile to desktop
When a mobile device isn't in use, Google Keep can be accessed as a Chrome app or as a website. Basically, no matter the device being used or the OS on it, there is always a way to access the app. There is also no limitation to how many devices this can be done with, freeing up the user to always have access.
Pro Allows photo and audio attachments
Notes can include multimedia attachments in addition to text.
Pro Both location- and time-based reminders
You can set reminders that bring certain notes to your attention when you arrive at a specified location or when it’s a specified time or date. Unfortunately you can only do one or the other for each note.

Pro Super fast to use
The focus on a minimal interface makes everything fast to use on both web and mobile. This comes in handy for when a note needs to be jotted down quickly as there is little to no load times or faffing about trying to get to a space where the note can finally be recorded.
Pro Includes character recognition for text in images
Google Keep lets users take pictures of physical notes and makes the contents searchable within the app. This can be a convenient time saver for those that do not want to type out the necessary info, but rather take a quick snapshot of it.
Pro Can share and collaboratively edit any item including lists Keep allows sharing any item with other contacts and editing them
Keep allows sharing any item with other contacts and editing them together at the same time. This way a team can work together in real time, no matter their location.
Cons
Con Does not integrate with Google Calendar or Tasks
It does not integrate with Google Calendar or other Google Apps with the exception of "Google Now."
Con Not good at all for longer notes
With almost no formatting options whatsoever it's hard to actually use Keep for long-form notes.
Con No notifications when tasks are added to shared lists
Although the ability to collaborate on lists is advanced, Keep will not let you know when another person adds an item to a list you share.
Con Cannot share groups of notes (e.g., labels)
Google's equivalent of groups are labels, which can't be shared. By comparison, Trello allows you to share boards with others. Trello also supports grouping through teams. Google Keep has no such concept.

Flagged Pros + Cons
Pro Useful Android home screen widget
The Keep widget lets users quickly see existing notes and add new ones.
Con Not libre
This application is proprietary, and thus cannot be modified or freely distributed.
Con To-do list does not synchronize with Google Tasks
The to-do system of Google Keep is separate from Google Tasks. Because of that if you rely on Google Tasks, all Keep to-do items have to be manually copied Google Tasks as well.
Con Organization is limited to just multiple tags for notes
It makes the user interface more cluttered, and navigation gets more difficult.
