Performance
With that kind of horsepower, both the Mercedes-Benz GL-Class and the Lincoln Navigator L are true sportscars.
Handling
With its tighter turning radius, the Mercedes-Benz GL-Class is quite certainly nimbler than the Lincoln Navigator L, something to consider if you do a lot of city driving; on the flip side, note that a vehicle with a tight turning circle may feel a bit twitchy on the highway.
Drivetrain
The Mercedes-Benz's engine is substantially smaller than the Navigator L's. Bear in mind that a smaller engine usually has to work a little harder; however, smaller engines typically get better gas mileage.
Torque is roughly equivalent to acceleration, and in this respect, the Lincoln Navigator L isn't much more powerful than the GL-Class.

There's no clear winner between the Lincoln Navigator L and the Mercedes-Benz GL-Class when it comes to transporting cargo.
There's little the Navigator L can tow that the GL-Class cannot.
Comfort
While the front cabin in the Mercedes-Benz GL-Class offers a bit more head room than the Lincoln, there really isn't much of a difference.
While the rear of the Mercedes-Benz GL-Class provides a bit more head- and leg-room than the Lincoln Navigator L, there frankly isn't much of a difference.

The GL-Class's shorter wheelbase may produce a less-settled highway ride but a more agile feel in daily traffic than the Lincoln Navigator L.

In terms of MSRP, the Mercedes-Benz costs roughly as much as the Navigator L (though the Navigator L is a tad cheaper).
