I disagree. The contention is whether LEDs can color LEDs as well as T5/MH. Does it matter if the tank is wall to wall Acropora or full of aptiasia with 1 acro colony? Disregard all the Montiporas in @wpeterson's tank and just focus on the sticks. Am I wrong or did he win the acro grow out? Where are the pictures from that? Seasoned acro growers are going to be reluctant to switch. Because of all the acclimation issues already mentioned. Who is going to risk thousands of dollars trying something that may kill off their colonys!?! Look through tanks that are on LEDs from the start and sps dominant. You will see just as vibrant colors as T5/mhs as well as just as washed out and bleached as t5/mhs. In fact, my pink mille has gone from a pale pink color to a deep pink after switching to AP700s from Hydra 52s. Frag came from a tank lit by Radions.
