It's not all about PAR in the end. IME, it seems like the quality of the light that comes from MH exceeds that of T5s. I don't know why as all the little numbers we can test for seem to indicate that they are essentially the same kind of light. I have definitely noticed that newbies have an easier time accomplishing great color and growth with their corals using MH lighting than T5s. I really can't explain, but it's a trend I have really started picking up on in the last couple years as T5s have become more and more popular.
I used to be a diehard MH, then I was diehard T5, and now I think there's a place for each type of lighting.
