The Schmidt SON28 is especially recommended if you want light at especially low speeds. It will produce front and rear light starting at about 7 mph, whereas the Shutter Precision will start at about 11 mph. And that's the Schmidt's one distinct performance advantage over the SP, to our knowledge. And remember that the bigger your wheels and tires are, the faster you'll need to be going to make light happen, so if you're riding a 29er under 12-13 mph for long periods, the Schmidt may be best for you.
