Unless you guys are comparing PAR of T5 setup vs MH setups using the same number of watts then you have no debate. MH are more efficient. There are really only three points in which T5s could be considered "better":
1. They have prettier fixtures.
2. You can customize the visual appearance of the light by using different combinations of bulbs. More bulbs = more combinations.
3. Less heat, but not by much.
On that note. I have T5s right now. I've had MH in the past. I prefer a combination! T5s are really good actinics!!! Tee hee hee

I'd have to debate both those.
Neither are true.
