Glad I chose the Armada
 Needed to tow horses. Looked at the Suburban, Expedition, etc. The Armada had more standard safety features and more convienence features than the others. Second row legroom beats any other SUV (by far), and the nav/voice system is best on the market. However two areas could be improved: 1) the suspensions "shudders" when driving over broken pavement.  2) the seats aren't very supportive - although the truck has little body roll, the unsupportive seats magnify this effect. I'm fortunate enough to have owned LX 470s, RRs and G500s and I still find myself driving the Armada most of the time. If you prefer a "richer" environment, consider the QX56.
