What Software/Platform for Print Publishing?

Howzer asks: "What's the deal with publishing these days? I remember clearly the old Quark vs Pagemaker wars, the winner being Quark, on a Mac, end of argument. But that was the late 90s. These days the three products I seem to be hearing about are Quark, Publisher, and InDesign. I'd love to get some opinions on platform/software and the current state of play, as it seems I may have to have an opinion on this soon. I thank you, the designers who'll soon be working for us thank you, and the people who'll be reading our 120 page glossy monthly magazine thank you." What publishing software gives you the best performance and features for the money?
