I have them and there is most definitely a significant difference between the LED's and the Xenon's. You can really only see the difference when they are next to each other shining down the same road. Ive done this with my M and My X and its significant. The LED's make anything reflective pop out of the night much moreso than the Xenons. They do look way cool as well.
