I used MagicDraw in a previous job, it's decent. We had it setup so that we actually generated C++ class's from parts of the UML. As well as generating powerpoint and word/pdf documents from it. MagicDraw also comes with its own version control system so that everything can live centrally on the companies server. I do wish that it integrated with Git, and that the app was slightly faster / less bloated, but all in all; it was a much better experience than Visio & PowerPoint. These days I'm unfortunately back on PowerPoint architecture. Enterprise Architect and MagicDraw are as far as I know the two most popular UML diagramming tools.
