I like that it's easy to set up, doesn't require any plug-ins or additional addons in order to work properly (it works fine with WordPress). It has many different options but you can only customize some of them through their own dashboard interface which isn't very user friendly. They could make this more intuitive by adding an admin panel where we don't have to go into our live site every time there needs to be changes made. The one benefit they do offer though are tutorials when first starting out if needed. But overall it seems pretty straightforward once you get used to how everything fits together. We use Google Analytics so having comments added via GA was great!
