Best growing method

What is the absolute best method for growing indoors if quality is your biggest concern? I'm sorry if this has been asked a thousand times before, but a google search still yields no satisfactory answers. My guess is some sort of aeroponics. What's the best model/setup for such a method; I mean, what product(s) should I buy? I don't care about the learning curve, time consumption, or start up price. What strains grow best under such a setup? I'm looking to grow top-notch strains like White Widow and/or Northern Lights under a 600W fixture. And again I say quality is my biggest concern. Yield is nice as well, but not at the expense of quality.
