T5 or LED?

I have a 55 gallon reef tank that is currently using a 4 bulb T5 unit with ATI bulbs. I am thinking of making the switch to an LED fixture. What are your thoughts?

I have read about some not feeling that LED's are as effective as T5 in terms of power. I have also read the LED's make the water look more luminous and corals more colorful

Any opinions are welcome. Thanks
