Realistically for best color, growth and over all initial effect (as when you first walk into the room with an SPS tank) a MH and T5 combination is what I believe to be the "best" however "best" is a relative term and the benefits LEDs offer these days are just too large to ignore. I'll sacrifice some colors that don't look quite as good and how the tank doesn't appear as bright as before (might be a benefit to some), growth is debatable but when you're using a fraction of the power before it's hard to really care about a few mm. I could never go back to MH, T5s maybe but doubtful.
Plus LEDs are cool, there's even a special club for losers that don't have them, enough said.
