All I can tell you is the 13 seats are better. They look the same, but for me they are so much better. I am 6"2" 255lbs, so that might be a factor also. The 10 I never liked the seats, griped to the wife from day one they were not comfortable to me and a hundred miles in them was torture. We were 5 minutes into the test drive on the 13 and I told my wife the seats were better. She didn't notice it then, but on the 80 mile drive home she also commented on the seats. We took it on a 350 mile trip to our vacation home, and I had no problems riding in it that far. Previously in the 10 we would have been stopping much more often.
As for CUE, all we do is play the radio, use the bluetooth and navigation, and all that has worked fine for me. If you are a techno geek then maybe it isn't good enough, but you can't please everybody. Also, even though we don't use it to it's potential, it sure looks cool, and the backup camera comes on immediately. The 10 there was considerable lag time for the screen to come up and the camera to come on. Once when backing out of a parking space a car ran right up behind me. The screen wasn't up yet, but I was saved by the rear parking sensors. I personally really like the fact you don't have a screen sticking up from the dash.
