Coming from a Land Rover LR3 with all rear seats that fold flat, I can tell you that I much prefer the LC setup. Don't get me wrong, the fold flat is great for a few things; however, what I found is that it is such a pain to fold flat, I rarely did. See, you will likely have a mat over the 3rd row when it is folded. Then you will likely have things on the mat like storage box, etc. IN addition, you may have tie down straps that you need. . . The problem is, is to simply use just one of the 3rd row fold flat seats. . .all that stuff has to come out of the truck.
As I said, now that I have owned both, I much prefer the LC set up. In my 2013 LC, the mats and gear in back is all designed to be able to stay in place whether the rear seats are up or down. It is a game changer. I rarely used the 3rd row in my LR3 because it was such a hassle. Now I always do in my LC.
