I use both. Bright Local has nicer looking reports and does a good job of handling both organic and local rankings. The Interface is quite polished and easy to use. You can also setup automated reporting. I believe there is still a free trial period to get a feel for the tool.
Places Scout excels as a research tool. It has a feature that helps you find potential clients based on keywords, search ranking, location and other criteria. Mark's support is really top-notch. He puts out fixes and updates continuously. The price point of the program is also quite low compared to other tools (it's an annual subscription). Although I haven't used it much, a lot of work has gone into the new Reputation Management module that works similar to Darren Shaw's Local Citation Finder.
