Getting started on Arduinos with Atmel Studio 6

The tutorial states, "Atmel Studio is a great choice for users that have outgrown the integrated Arduino IDE. The Arduino IDE does so much under the hood that it can actually be quite limiting for experienced programmers". I'm pretty competent in C and don't see what benefit I get from the Arduino IDE, apart from access to a pre-compiled Arduino library, which surely could be made available by the community. In what way would the Arduino IDE be easier for me?
