If you want actinic supplemation only VHO is the better way to go on almost every tank i have seen. at least. I think one benefit in the T5 area is the sleak look for an open top tank. MH have some nice units but say ati's units just look spiffy, they seem to be a little more current on design appeal thank MH units...not all but in general. I personally think a tank looks nice both ways, depends on the tank
I have seen tanks I would love to say were mine with All LED, VHO, T5, MH etc. When you get to arguing about aesthetics, there is never a end. Its the old ..i may not now...but i know what i like.
If you want to argue cold hard facts...you need to find them realiably then, no disussion i have ever seen has anyything other than personal opinion oh energy usage, bulb replacement etc. Bulbs both kinds can be found cheaper ands at least equal if you look around it seems.
