As far as coral growth, I like them both the same. Both have shown explosive growth on my zoas, acans and chalices, as well as the few sps I have. The TaoTronics blue leds seem to be more royal blue-ish, whereas the reefbreeders blue seems to be more of the actinic blue we are all familiar with from T5's. My corals don't seem to care one way or the other.

I'm planning on buying two more reefbreeders fixtures within the next month, to replace a T5 fixture.
