Somehow the XT-R feels softer than the EC-R and smoother. A bit more refined so to speak. The extra thickness is no problem and it doesn't affect the comfort level at any point. The XT-R feels stronger and looks much better too. However the EC-R is half the price of the XT-R so if your looking for a new mouse pad, any of these two will do just fine. But it's still a matter of would you spend twice as much for the XT-R if you can get the CE-R.
