Integration with Google Services
The biggest advantage when people use Google+ is its integration with Google services. The social networking site’s features and tools are built into almost all of Google’s existing online services from Search to Documents and Video (Youtube).
Besides, it is already integrated into the navigation bar at the top right of nearly whole Google products, which helps users manage Google+ events (updates, messages, etc.) and share content with friends without leaving Google service they once used.
People, who use Google’s free services like Gmail, Docs, Search, etc, may be interested in new features and advantages of its social networking
Better Friend Management
Google Plus’s Circle concept is more in line with the way you make friends in real life. Facebook’s Groups feature is “built on”, allowing you to form groups of friends, while Google Plus’s friend “Circles” are the bedrock of its platform.
Google Plus is better than Facebook in friend management
Better Mobile App
With the Google+ mobile app, you may recognize that getting content from your phone to your social platform is easier, cleaner and more functional if you’re an Android user. Google will seek more and more ways to make your Android phone a seemless appendage of your Google+ social platform.
Google hopes to use its huge Android user base as a wedge against Facebook
Easier to Find Stuff to Share
Google Plus’s Sparks is a typical feature that differs from Facebook. It offers users an instant wellspring of relevant information to share with friends, while Facebook users must leave the site to find shareable data or wait for their friends sharing it with them because the social networking site has no search engine.
The question "how do I find stuff to share" is immediately answered with Sparks
You Can Get Your Data Back
Facebook is infamous for its poor stewardship of personal data and its users find it hard to permanently delete your Facebook profile. On the contrary, Google allows users to pick up all the data they’ve banked at Google Plus and walk away.
With just a few clicks, you can download data from your Picasa Web Albums, Google profile, Google+ stream, Buzz and contacts
Better Photo Tagging
The way you tag people in Google+ is similar to that in Facebook. However, the big difference is that when you tag someone, you see this note: “Adding this tag will notify the person you have tagged. They will be able to view the photo and the related album.” Facebook, on the other hand, does not warn people who they’ve been tagged and give them an immediate chance to remove the tag.
Google+ also avoid using facial recognition software that Facebook now runs to automatically identify people in photos uploaded to user albums
Strong Group Chat Features
Google Plus’s Hangouts feature is easy and creating ad hoc group for a little chat seems like a natural and fun thing to do in a social networking setting. Besides, the new Huddle mobile app makes it easy for mobile (Android) users to start up group text chats. Facebook simply doesn't offer these tools.
Google+ obviously beats Facebook in the area of chat
Safer Content Sharing
With Google+, users can assign a privacy level to each piece of content they share, instead of using a pre-set list privacy settings to govern all shares. For example, when you share an article or upload a camera image, Google+ gives you choices of which friend circles you’d like to share that content with.
Safer content sharing is among typical features of Google Plus, which Facebook may not do well
