Welcome! Lighting is such an individual decision! They both have ther advantages.. T5's offer a very economical powerful light source, with limitless spectrum and CRI options by simply changing the order of your bulbs sequence, etc...
Halides look awesome... Clear, crisp and shimmer, but they are hot and very expensive. You "MAY" need a chiller on your setup with them to add the overall cost. Even with Halides, you will probably want to add some supplimental VHO or T5's for Actinics or just general viewing when the Halides aren't fired up.
Good luck with your decision. If you select T5's, I would put 6 on your 40. I'm sure other with chime in. Does the 40Breeder have a center spline? If not you may bee able to hang (01) 250 watt Halide and add a few T5s for the best of both worlds
