I went with the Bookshelves because they were smaller (which appealed a lot to my wife), less expensive, and had lower frequency response (side effect of being ported rather than sealed). As long as you aren't going to have clearance issues with the rear ports on the Bookshelves, I think they make great front channels. In my case, they need to be a good distance away from the wall anyway because of my room layout, so the ports have plenty of breathing room. The LCR's, on the other hand, can be wall-mounted without issue because they are sealed.
