His Escalade has the 6.0 motor and 3:23 gears and he said it is not a good combo pulling a 28ft Outback not sure but I think he said it was just under 5K in weight. Next TV for us will be a Suburban or the Yukon XL larger and definitely more solid on the road no matter what I tow.
So you are right, the Escalade ESV and Yukon XL Denali both have 3.42 rears from 07-14 and the 2015+ for both have 3.23 gears. However, the 15+ also have 40 more ft/lb of tq and an 8 speed transmission (vs the 6 speed). So I think it slightly makes up for the more highway rear gear.
The Suburban doesn't get the 6.2 nor the 8 speed. So to me, it's the least capable of the three GM's (but not by much IMO).
You really can't go wrong with any of these full size SUVs of any brand. They are so competitive and spec'd so similar that it comes down to preferences of exterior/interior look, mpg, comfort and reliability.
I re-emphasize my earlier recommendation to look at a long version SUV for the extra room and longer wheelbase. Glad I went that way for sure.
The full size SUV I'm most looking forward to is thr 2018 Expedition that will be on the aluminum body and all the interior upgrades of the new F150. With the EcoBoost, and maybe the 10 speed from the new Raptor. It should be a crazy SUV, with a huge sticker price to boot!
