The Navigator if far superior to the Suburban in every aspect. Much smoother and quieter ride. 460 ft. lbs of torque make them quick. 3 to 4 more inches of legroom in the 3rd row making it comfortable for adults. Flat floor board in the 2nd row (no drivetrain hump like the GMs). Power running boards make for easier boarding. And I left the best for last... you dont have to replace the transmission every 100k miles like you do with the Suburban. FYI, GM lowered the powertrain warranty on the Suburban from 100k to 60k miles because they cannot build a reliable ******. I just paid $57,000 plus tax, title, license for a 2017 (2WD) with 100k bumber to bumber warranty. Literally no comparison. For Uber yes, but for privates, my clients love my upgraded fleet.
