I have always liked VHO. If you do not want to spend the money on a halide system than VHO is the way to go. Thay make kits with ballasts that will fit in your canopy. Or, you can order them seperatly and DIY. Either way is easy.
Some like PC. I had them on my 75 reef and never saw alot of growth, except for the coraline algea. As far as my corals though, they lived and opened well but never really grew that much. Once I put VHO on the tank, it exploded with life. My leathers started to grow and my brains started to expand.
This is just my experience though, some others hae had good luck with PCs as well.
