my brother had a tahoe when i had my traverse. we did a road trip with his and the cargo space is almost comical. the traverse isnt huge but its reasonable. the third row on a tahoe is almost useless for an adult. the leg space is almost none. the traverse is cramped in the third row but doable.

one thing the tahoe did have was more width inside. not major but noticeable. im pretty sure there are other benefits to a tahoe but space wise traverse was a better move.
