Personally I like the PFO brand stuff. There reflectors have on of the highest output designs. They will also do custom work and are very nice to deal with. Carla at PFO who i have delt with for 2 years has always been nice about fixing any problem I have had. I work in a fish store and I have sold at least 100 different systems. I have also delt with Hamilton who I have the exzact oposit reaction with. many people have delt with them and had good luck. From my experence I have not. Current is ok, so is coralife. Nothing real stands out abot them except there price. There is also Sunlight Supply who is anther great company to deal with. Great reflectors and great customer service. If you don't mind me asking what size tank this is going on? Are you doing sps, lps, soft or mix? That can be a big infulence too.
