My MIL bought a brand new Enclave and I drool over it. IMO, it is not the same price point as the others you have listed.
We were recently in the market for a 3rd row SUV and looked at the above - except the Edge, which only seats 5. I ended up with a Mazda CX-9. It's built on the Edge platform but is longer with a 3rd row of seating. I absolutely love it and for the price of a gently used one, it was a great value for us.
The Traverse was the other one we tried to purchase but couldn't find one in our price point. They were still pretty new when we were looking. The Acadia has some major reliability issues according to Consumer Reports. Matter of fact, I inquired on several and had them email me the Carfax and every single one of them had an issue. Maybe the new ones have been improved, just something to keep in mind.
Have fun shopping!
