Personaly I feel the best bang for your buck is MH lighting with VHO actinics. the T5's I have seen at a couple LFS here have been totaly disapointing.. I guess they would be better than NO bulbs but thats about it.
for pure intensity you can't beet the MH lighting.
as for your question about your 150's they will be fine for a tank less than 18" tall.
