When it comes to usability, vegas pro delivers perhaps the most intuitive, easy-to-use interface that the big boys, such as premiere pro and media composer, can't beat. Sure, vegas doesn't offer the most features, but due to its simple workflow, I can do considerably more work in a given time period as opposed to using premiere.
