You get better coverage out of 3w LEDs. I just went with 12 royal blue 1 true blue and 8 natural white luxeon es (steves leds) for my 27g and they look great. I went with a heatsink from rapid led though because by it self looks a lot better and is easier to wire on instead of many tubes. I also used steves led drivers and power supply for the ability to get maximum efficiency out of the system. I also liked the idea of separating the psu and drivers so that if one fails I can just replace that part... It is more work though going that route.
Anyway I would go all 3w for best spread of light.

I've been running a 10 watt LED diy fixture for over a year. Works great, coverage is fine. It's all a matter of spacing, height of fixture above water & possibly optics, whether 3 watt, 10 watt or larger multi chips. Check the link to my build below fo mo info. Many multi chip leds 10 watt & up are now available with a mix of colours on the same chip.

i ran 36 3watt diy led half blue and half super white, it worked really well, i had amazing coral growth and the coloration i wanted, i also ran two dimmers to give me full control. i just finished my new tank build and have my DIY LED fixture in the closet, bit of a waste.
