OK, I'm going to tell you anyway.
Results with LEDs usually mean slightly less dense bud and just slightly less wgt, but more trichome production and increase in potency. Blind taste testers have always been able to tell the LED stuff was better. (sighted testers have not been used yet)
Another plus with the LEDs, no need to run duct work and use (in my case) a 400+cfm fan to cool them (more electric use). The LED setup raises bloom room temps a couple of degrees only above ambient. The other big plus, with less radiant heat generated your medium won't dry out as fast, instead of watering ervery other day the LED plants go a week. But that's not all....because less moisture is cooked off from the pots the amount of salt build up is reduce tremendously.

Here's a couple of pics of some LEDs. How about 2 TI problooms for a total power consumtion of 660watts vs 1150watts total for a 1kw HPS.

See, a side by side comparison of LED and HPS. I've actually used both.
(I also use T5s, love to overdrive them)
I agree the quality is better but it is till to soon to swich out your hps.I have 2 90 watt leds growth is veary slow but healthy dark and pure sugar.If using led i would do a small grow(cabinet) and stick a hair dryer in there every once and a while to make it thirsty and take up some nutes.This is just my opinion.These lights are awsome but do not compare to hps.I think with my set up i am going to run 2 90 watt into early flower then turn on a 400 watt hps while still running parts of the ufo spectrum in a 4x2x6 tent using see of green.The big mammas are just going to half to wait to be put in the dirt out side.
