The ones from LEDsupply are genuine whereas there has been some speculation that the ones from DE may be knock offs. I have also read that people have ordered from DE and they did not get what they ordered.

If you are looking for a better deal on LEDs try http://www.nanotuners.com they have them for a couple bucks cheaper.

I've had pretty good luck with Deal Extreme. The Cree LEDs I have purchased from them have been excellent and plenty bright. The main difference between the two will be the star board PCB. The DE ones are cheaper lower quality ones. That will most likely not be a problem but I have had the odd cheap one delaminate. And you always pay a premium when buying in North America vs. Asia so that accounts for some of the price difference.

But as stated above, Nano Tuners has a great deal on XR-Es right now if you want the better PCBs.

P.S. You also will not find royal blue XR-Es at DE. So you might as well buy them all in one place such as Nano Tuners.

I agree. I have bought LEDs from both DX and LED supply. The DX ones give off the same color and intensity as the LED supply ones, but the boards are quite bad. A few of them have had the solder pad come off when soldering making them essentially useless. You get what you pay for.
