I'm doing a DIY fixture for my new tank and I can't find a downside to LED. For all the statements of "Where are the nice tanks"...people obviously aren't looking very hard as LED has been around a long time and some amazing tanks are represented out there.
As with all trends...people try different things until they find the one that works...I guarantee the first people using MH were running things in the 6k range and thought it was "awesome".
With the right combination of bulbs and dimming, LED's can be made to fit almost anyone's color choice.

Just my 2 cents though and I encourage everyone to follow the lighting method of their choice.
