The best feature by far is the ability to schedule posts on Google Plus. I personally appreciate the browser plugin, so I can cross post content from Facebook to Google Plus, because I can schedule posts in advance on the Facebook platform, but not on the G+ platform, so I cross post the schedule through the plugin integration. The next best thing is the preset schedule defaults, which allow you to post on social networks on preset times.
What I dislike is the inability to archive social media accounts that are inactive. There is no other way to add new social accounts, without deleting the old ones. Deleting accounts destroys years of metric data that could be useful for case studies. We could also possibly re-activate an archived account, but that isn't possible without the option to mark accounts inactive, or archived.
If you'd like a great tool to cross post content from Facebook to Google Plus, Pinterest, and Twitter, the Buffer browser plugin is excellent. You can schedule posts on platforms that don't support scheduling. That makes social media management far more time efficient.
Without a scheduling apparatus on both Pinterest and Google plus, Buffer offered a great solution. You can also assign team members to accounts, so that Twitter, Pinterest, and G+ accounts can be serviced by more than the primary owner. This makes social media management easier and more efficient, because of the aggregation. It is a better interface compared with Hootsuite as well, and I prefer it.
