most of the led units, chinese, offbrand, or 700 a unit will grow good coral to varying degrees, the biggest thing you cant get with offbrand right now are the new lenses a couple companies are using which diffuse the light better.
It comes down to the features you want, how many color channels, built in timer or full programmable, wifi/bluetooth? led makeup(#'s of different spectrums) and layout.
in my experience everything grows good under a standard chinese box with manual timers in the shallow frag tank, and reefbreeder style lights with built in timers have made the display look great and coral, mainly sps, has responded very well to the change from a heavy t5/led hybrid setup.
