What's better HQI or socket style metal halides?

[JR Aquatics]

;-) I am converting over to Metal halides from power compacts. I was looking for any recomendations on which style is better or the downfall/bennefits between HQI and socket style metal halides. I am looking at getting a Blue Wave VII - Dual HQI Ballast and Reef Optix III plus HQI Reflector Halide Lamps (two) 250 Watt for a 90 gal mixed coral tank. My LFS buddy believes that the HQI style has not been out long enough and recomends me getting the screw style. I am open to any suggestions.

HQI All the way!! They say the HQI 150 is like a 250 socket and the 250 is like a 400

So everyone agrees that hqi are better than mongul screw style.

Is there any brands that are better than others? (Cost is a consideration)

Actually that's not the case all the time, go here: http://www.reeflightinginfo.arvixe.com/ and do a comparison between any 2 bulbs.
