I think the 2015 Escalade interior is a step above the interior of the 2013 model. It is nice to see the darker brown and black leather instead of the beige. And I think that the centre console looks better having more texture instead of just being flat. I think that the Escalade is doing a good job of competing with the QX80. I don't think that it is the interior design that will be the deciding point between the two vehicles. Price, exterior design, and options are the bigger differences.
