Pros
Pro 15GB of free storage
This space is shared across Drive, Gmail & Picasa, but Google Docs documents, Google Slides presentations, Google Sheets spreadsheets, Google Drawings and Google Forms do not count for this.
Pro Extended functionality via apps
Third party Drive applications running in Chrome can add functionality such as image/video editing, project management, flowchart creation, etc.
Pro Indexes images
You can search images by object, place, or face when they've been added to your google photos collection. Google Assistant also helps you find screenshots that could be archived, images that aren't in the correct orientation and pictures that would work well as animations or albums.
Cons
Con No Linux desktop app
Google as of yet has a client for Linux, leaving many who use the service forced to use third party apps or the webpage.
Con Terms and Conditions allow Google to own anything on Google Drive
They can create derivative works, they can perform it, they can modify it, and they can publish it at will. There are many other specific rights they take over your product. Read the Terms carefully and compare with ANY others.
