I'm not sure what "better" means. I certainly think they are "cooler" than T5s. But, T5s grow corals quite well. So, they aren't substandard or anything for your actual growth needs.
Sorry when I say better I just mean some lighting will work, but won't maximize your corals growth. I find that the T5's are great, and I really like them, and I see the growth and health of my corals, but is there better?
Thanks for all the help by the way!
