Having to be a current passenger of the 2001 Lincoln Navigator and a week in an 2008 Cadillac Escalade I would go for the Expedition EL hands down. In my opinion, the Expedition looks a lot better than the Yukon, more comfortable, more roomy, and certainly more practical. The Expedtion is actually the largest Large SUV in it's class with the Navigator. The Yukon in my opinion has a very rediculous transmission as well. It certainly misshifts a lot (ex. Down shifting two gears, than upshifting two gears for no reason) as well. The Expedition transmission is very good due to the fact it shifts very smoothly. Although I am going to base this experience from the luxury SUV versions of those vehicles, this should give an idea of what both are like.
