X7 is nicer on road, better handling, better build quality by a little bit (WL is the best American quality from what I've seen).
Audi Q7 is similar to the X7.
Range Rover (pick your model) offers similar luxury and comparable off road capability to the GC, but at higher cost and worse reliability.
The new Sequoia coming out this summer will have more power, and be roughly as capable off road, but likely won't handle on road quite as well, but will probably be significantly more reliable, even in its first year. Tech not as good.
Tahoe has far less tech and cheaper fit and finish, but the diesel gets FAR better gas mileage (double what my Hemi Overland 4x4 gets).
Ford's Expedition feels/looks cheaper to me (interior) and doesn't have most of Jeep's tech either.
It's looking like I'll have a deal to replace my '21 with a '22 shortly. If the replacement could be had with the new I6tt engine, it would still be the prefect 'best of all worlds' vehicle for my use case (off road, towing, on-road handling, all the latest tech and a great sound system).
I will likely replace the '22 Hemi Overland I get with the I6tt version whenever it's released, pending how the new engine acquits itself in the Wagoneers. I live at high elevation and the turbo motor doesn't lose power up here like the naturally aspirated motors, and should deliver better fuel economy than the current V6 to boot.
