My 2 cents on the topic.
LEDs taught me alot about growing and understanding my plant's wants as well as needs. And I would not trade my LED panels for the world...However, I also own a 400 W HPS/MH system, and I have a greater appreciation for that set up based on my experience with the cheaper LED set up I have.
CFL, LED, or HPS/MH...your situation will always appear to be simple to some, but a complete kunundrum to others. If you have the space, the budget, and the commitment, I say get the HPS's and don't look back. In my humble experience, the LEDs are what's "Sexy" right now. If you have the money to spare, then HPS/MH is the way to go.
Again, I'm not knocking anyone that's getting their hands dirty and doing the work, LEDs or otherwise. I am simply of the mindset that quality trumps quantity.
