We use Project Pro 2010 and are implementing Server. I have referenced the Microsoft site extensively for background – they have lots of white papers and a whole series of videos on the product.
Why are we implementing Server?
Enterprise resource management, including the ability to manage current workload and plan for future capacity
Project prioritization, the ability to select projects based on a defined and repeatable process
Metrics and reports at the project, program and portfolio levels for different audiences (using third party tool for some of this)
Forces us to improve our basic project management capability
Standard toolset for all our project managers
Project Server is a big investment and a lot of work to implement. You are right to weigh the pros and cons to see whether the system is right for you.
