Personally I would recommend Indesign over Publisher at the moment. Too many little issues with Publisher if you are doing pro work. The big one is not being able to place a PDF file in Publisher without it wanting to make it editable. This can cause so many issues and create a lot of problems. For me that is the biggest one right now. Would be nice to have data merge and a few other things but those would all be putting the cart before the horse in my opinion.
