Welll I have a 150 gal reef and I first ran 4 - 72 in VHO did mainly soft corals I now run 3 -250 watt mh 20000 k w/ 2-72 in VHO and love it can have what ever and all looks great. So that would be my suggestion over the choices you've listed. Though both set ups listed are running about 600 watts which is not bad though mh lighting gives you a great look with the shimmer and you would be able to keep corals that need stronger lighting needs. Good luck!
