As someone who is coming to the end of a lease on an XT6, avoid like the plague!!! It is a GMC Acadia with a Cadillac badge. We had the Acadia before and it was a much nicer car that cost less.
I would 100% look at the new Pathfinder, the tech is so much better and will be built 1000% better. Loads of road noise, constant squeaks from the rear, 2 or 3 recalls in the 3 years we have had it. You are basically getting a 7 year old car, it is due to be replaced any moment now.
At that payment I would be looking at an Infiniti QX60, which is a more luxurious Pathfinder. Loads on dealer lots right now.
