I always maximize my browser windows. There are a handful of applications that's true of, browsers, video players, IDEs, and games for the most part always get the fullscreen treatment. Chat clients, terminals, certain kinds of editors, etc. I usually tile. Of course my screen is only 1920x1080 so results may vary (I miss my 1920x1200 monitor, but they're so hard to find at a reasonable price now).
