If you're going to compare a Yukon or Suburban to a Ford, it should be the Navigator. The Navigator is far superior to all of them imo.
I'm not crazy about the look of the Navigator, but that's just personal preference. The additional $10,000 price tag however was enough to shoo me away. I also looked at the Escalade. That was an additional 12 grand and I really don't care for its looks either.
