T5/MH is still top tier for coral growth. Now for ease of use (Getting the color you personally like), power consumption, heat that comes from the fixture, and coral pop, I think LEDs got that on lock. But ATI blue plus still the king of color spectrum that corals thrive under. I use an hybrid system so I can get everything, 2 ATI blue plus, 2 radions, and two orphek for coral pop.
