New Nano Build: ATI Sunpower T5 or EcoTech Radion Pro???

Hey guys
I just purchased a JBJ 30 gallon Rimless nano tank. I want this to be dominated by SPS corals.
I am totally torn with what lighting to use. I need help!
I am either going with a 24" ATI Sunpower T5 or EcoTech's Radion Pro LED.
Thank you!
