To be clear, I think if you are looking for an led fixture that has more than 2 channels of color control (the Photon V2 has 6), sunrise/sunset control, and a thin, cool, modern looking fixture, the Photon V2+ is by far the best value available. It also has quality leds (Cree and others) and it comes with both a hanging kit and legs.
The SBReef is a good fixture, but it is still the old school black box look that is rapidly starting to look very dated. Even the Radion looks old next to a Photon fixture and it costs way more!
Now if you are looking for something less expensive and don't care about 6 channels of color control, or the black box look will be hidden in a canopy, then there are several good fixtures that are less expensive.
