The Armada might have the worst gas mileage in its class, but it is simply the best full size SUV relative to the Tahoe/Yukon, Expedition, and Sequoia. None of the other vehicles except perhaps the Sequoia can match the overall performance, comfort, spaciousness, and quality of the Armada, and the Sequoia is flat out ugly in my opinion. I really wanted to like the Yukon/Tahoe and Expedition but their weak engines, cheap build quality, and handling left a lot to be desired (though the Expedition handles much better than the Tahoe/Yukon).
CR is a joke and has been for years. Like most companies that give opinions on products, watch where their hands are (taking cash from brands). Anyone that buys based on CR deserves whatever they get.
