I'm a big fan of how flexible Social Studio is - if I want a CS package for Twitter, I've got it. If I want to research a topic, I can easily set it up because it is also reliable in its feature set. It collects data from different sources and it is also very easy to download the collected data if you wish. It has a good overall user interface, is reasonably well organized and easy to use on a daily basis, easy to use and tons of cool features for case management and online reputation management with support for multiple platforms. Approval workflows are a great way to allow different levels of permissions for different people so from what I can tell it's pretty well done, being able to integrate with all Salesforce platforms is probably the biggest benefit.

A solid platform that supports a number of the most common social media platforms. Great for monitoring and providing insightful data (in not too much data) but end to end functionality can be restricted.
