Metal Halides vs. T5's vs. LED's vs. Ecofriendly Bulbs Which is better?

Switched from Mh (2x 400w) to LED about two months ago. I find that my sps is actually doing better now, more growth and coloring is great.
I think that just using blue and white led like many of the "older" led fixtures used caused issues by not having proper full spectrum, but now many led fixtures are incorperating different temps of white 4000k up to 14 000k, and other colors, like violet, red, green ect, which seems to be helping with growth and coloration issues.
It is a newish technology so as things progress it can only get better and better, and cheaper.
Oh and the leds I got are cheap chinese made ones custom ordered to try get best spectrum possible. They make my tank look great, it was like going from a plain tube tv to an HD tv.
