Which disc brakes new deore or new slx or other

Hi all, I have been trying to find some decent reviews of the new deore and slx disc brakes to see which is better bang for £ spent? Any one used either? I want to upgrade from my Avid Juicy 3's.

They are a massive improvement on the Strokers i used to have but do keep an eye on your pads, as the ones that came in mine seemed to be made of cheese once they got wet.
If you opt' for the SLX i doubt you will regret it.

The ice pads (finned ones) rattle like hell in the caliper. I stuck it for a few rides then replaced them with normal pads from Superstar - rattle gone. The finned part seemed very top heavy and as it sat above the top of the caliper it just rattled about.
