personally, the "T5s are flat" and "mh mades the tank look alive" is total garbage. That may be your opinion but dont try and pass it off as truth. The fact is T5s are an excellent way to light just about any tank. I have seen some T5 tanks that completely blow away similar Mh tanks. The colors are amazing with T5s and so is coral growth.
misinformation is worse than no information.
Beside not having the shimmering effect, T5 does produce amazing colors. For the short time I did have my ATI the SPS and fish displayed incredible color. The only reason for me to go back to MH is that the T5 did not do well in a 30" tall tank. For my next upgrade I will have a 25" or shorter tank and I will go back to T5.
Note: Friends and family raved about the beautiful colors it produce. I only had the T5 for 2 weeks. When I put the 2x400W MH everyone complained they missed the T5.
