That all depends on what type of corals you want to keep now and in the future. If your planning on all kinds of corals, to include clams, I would consider MH. LIke this one,  hombby, he usually has a 60" light . T-5 are not bad lights, alot of ppl have them with corals. I know when I had my other tank with PC's, I was limited on some corals and that would piss me off, so when I up-graded to my current tank, I didnt want that to happen again, so I got MH's this time. Good luck.
