If I needed a big SUV, the Suburban would be my choice over all others including the Germans...and the Escalade. The Suburban says, I mean business, the Escalade says I have a business.
I don't know about that last part - LOTS of Escalades being driven by folks who just want the notoriety of driving a 'Slade...financial wherewithal isn't necessarily part of the equation.
Although there's an argument to be made that at least the Escalade is honest - it's big, brash, garish and kinda tacky - but honest about all that. Whereas the Yukon Denali XL - supposedly the "tasteful" and value-priced Escalade - really isn't any cheaper, less ostentatious, or more "professional" than an Escalade.
If the new F150 does well, it will be interesting to see if Ford leverages it into an aluminum Expedition / Excursion. With more sheet metal, there might be even more potential for weight savings on these giant SUVs than on the trucks!
