FWIW, each of the fixtures I'm using have 119 Bridgelux 3w diodes driven at 1.26w and I've had great growth and color. I supplement the fixtures with T5 for a few hours each day, but not enough that it would support the amount of SPS in my tank if the LEDs weren't doing their job. I'm easily able to grow SPS on my sandbed in a 24" deep tank and the lights are suspended approximately 6" above the tank. I also have a Cree DIY setup over one of my frag tanks and I don't see anything to indicate that the Crees are any better. They are both good diodes and if I were to set up another tank, I wouldn't hesitate to use either brand of LED.
One thing that might be note worthy is that you have 357 3w bridgelux diodes over your display and twelve crees over your frag tank. Imagine you had 357 crees over your display I'm sure you'd see the difference then.
