I ran one of the cheaper 4 bulb units over my 90g. Great for soft corals but not enough for sps. A pair of 250w halides I put over the same tank was no comparison for the sps corals. Like night and day and the corals showed the difference.
Now the high end t-5 fixtures may a different story but never owned one. If you like the t-5 look, then I like the idea of adding another 2 or 4 bulb fixture. Guess it depends on how many bulbs one wants to replace every year and the corals you wish to keep.
