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

We are thinking of switching from Hamilton tech MH/T5 2X250 with Geismann 14000k, to Kessil 350's, running on a drilled 90 gallon, but we don't yet have an opinion on which is better, since we havent tried it yet. We are running 2x150 M/H on our 72 gall bowfront, and it is underlit. Might switch both. I ran LED on a small quarantine tank & liked it alot. We would LOVE to see someone elses tank with Kessils or something similar before we put out the cash. And/or hear opinions from people who have tried or seen both.
On a side note, our first salt tank was T5's only, and I liked the colour they gave, but hubby wanted the ripple effect of M/H.

The Kessil is a really nice light. I like how close the diodes are, really limits any color separation. Not sure how many you'd need on a 4' tank, guess it depends on what's in it.

I have 2 Gen 1 Radions on my 90 and they perform great
I've never used MH so I can't say which is better
I have T5's over a recently set up frag tank and they are boring as **** lol

T5 for now.

LED in about 5 years when the technology is better developed for reefing (and my wallet).
