Basing it solely off of the example vehicles for both categories - Chevy Suburban vs Jeep Grand Wagoneer, both are great vehicles. I personally drive a slightly shorter Suburban (Chevy Tahoe) so I'm naturally biased towards that and I like the way that the Chevy Tahoe/Suburban drives more than the way that the Jeep Wagoneer/Grand Wagoneer drive. However, the Grand Wagoneer is a little more luxurious with a bigger engine in it normally and it's kinda the new "IT" bigger SUV right now. I don't think you can go wrong with either category and once you get to a full-size SUV or higher, you are normally going to get a good SUV, unlike the compact, intermediate, and standard SUV ones that have a couple in each that are questionable/undesirable.
