I think either one will give you what you want. Your choice 
As far as bulbs go... For your tank any of them will work. It is going to be a matter of personal preference on what you think will be the most eye appealing.
Your tank isn't 50" deep and hopefully your canopy can be raised or lowered to accommodate your corals. You can also adjust the time the light is on. SO.... What I am saying is with either one of those retro kits you can use just about any bulb you want to, so get one that looks good to your eyes and then acclimate the corals to it. Enjoy,
Jim
