When I owned a Tahoe I chose it over the Expedition to get the rear leaf springs. The Expedition had rear coil springs which makes mods to improve load capacity or leveling much more difficult.
What is important is the final gear ratio and usually it is much too tall so as to improve EPA fuel economy numbers during testing. If one had 3.73 gears and the other had 3.21 gears I would go with the former.
Weight is only one factor when towing and Ford spells this out quite nicely in their towing guide. The frontal area of a travel has a huge impact on the total load on the engine and drive train for the tow vehicle.
I would go with a 1500 or 2500 class pickup with a crew cab over an SUV any day if planning to do serious towing.
Tahoe has had rear coil springs since 2000, when they switched to the gmt800 platform. So either one you choose now will have rear coils. If you are buy brand new they will both have independent rear suspension.
My FIL recently upgraded from an 06 Tahoe with 3.73's to a 2016 Expedition with 3.31's, both with full tow packages.
His trailer is a bit smaller at 6500 gross, but he told me it was an improvement in every way. Power, trailer handling, all of that.
Granted, it's 10 years newer. I'm sure a '16 Tahoe would do ok, but none that he found to test had a tow package. But the eco boost is a great engine for moderate trailer sizes.
