I don't know much about LW, so this may be misplaced advice, but many people use Vue as a place to assemble models made elsewhere into complete environments/scenes, with the addition of high quality atmospheres, terrains, poser models, vegetation, backdrops, billboards, etc. (and now with "Ecosystems"). I agree that a customized workflow with a customized toolset is usually better than trying to do everything in one application. Depends entirely on your goals, of course.
