I'm afraid I don't buy the explanation that once you get your Ph.D. in GTD you'll see why Omnifocus is a better product. All you have to do is look at the screenshots on the website to see that OF gives you too much information.

GTD is about simplifying your process so you can spend your time doing things that move the ball. It relies on your having trust that your system has retained all you've put in it and has categorized in a way that will present you with something when its time has come.

That's why I use Things (and I used OF for quite a while before I changed two years ago). I can trust Things, and I very rarely revisit my process itself. That happens every 3-6 months, and then I make a minor, happy improvement.

With OF, I didn't trust it, and I found myself tweaking my process almost weekly. That went on for months, and I never got comfortable.
