If all your work could be written on slips of paper, tossed in a bunch of fishbowls for different areas of responsibility, and then done by plucking random slips from whatever fishbowl caught your eye, OmniFocus brings a lot of machinery to the party that you probably don't need. However, if you have many tasks where ordering is important, need to be able to select tasks to do next based on availability of resources (contexts), date, available time, etc. then that extra machinery in OmniFocus comes in handy. You can use OmniFocus in the former situation, of course, but something lighter weight might be more convenient. If you want a lot of structure in your setup, OmniFocus will give you ample opportunity to indulge :-)
