Toyota:
Land Cruiser more than the lr3/4 length front center consol to tail gate. Even more so in Sequoia with 7 ft. Both very much 4x4 platforms. Both can take 33" tires in stock form prior to any of the numerous lifts available. Lockers available for both, front and rear diffs. Seats have to be removed for optimal cargo space.
Lexus: 570 (Same as Land Cruiser, but nicer seats and some other options)
No so fast! Front console to tailgate is not a measure of cargo floor space. Trust me. I didn't just research the Land Cruiser/570, I owned a Land Cruiser. The problem is that all you can do with the middle row is roll it forward up against the front seats leaving shortening the cargo floor space by about a foot. Then you need to consider the space taken by the 3rd row which in current models is a PITA to remove and on the 570, given that it is power fold (well, partly fold), they really, really don't want you to remove it. And if you do then, well, you don't have a 3rd row you can quickly/easily use when you need it.
NO, the Land Cruiser/570 do NOT have the same length of useable, flat cargo floor space.
On the topic of 3rd row seats, do the following comparison. with the 3rd row deployed, "stand" in the footwell in front of the 3rd row seat.
I highly recommend spending some time inside of each. Take your tape measure and do your own measurements. (Car makers try to find clever ways of making the dimensions sometimes look better on the marketing brochure than in real life.) But also sit, stand, enter, exit. Imagine loading. If it is important lying down. Deploy the seats. Fold them up. Consider the variety of ways you can configure the cargo area for your needs and how easy (or not) it is to do so. I knew what a LC was capable of. But to be sure about the LR I took some of my gear down to the dealership and put it inside - on the showroom. I needed to see how it would fit. For what I needed, it wasn't even close. And having lived with the LR4 now for nearly a year and 30K on all sorts of chores and adventures I will never go back to Toyota until they address there cargo space issues.
As for off road capabilities it is about more than just ground clearance. As for ground clearance the LC has 8.9". The LR4 has 9.5" and can go to 12 if necessary. Yes, that is stock on the LC and you could put on larger tires and lift it. Approach, departure and ramp angles are not as good. Turning circle is a foot longer. It is 5" longer.
Are the LC/570 bad offroad? Of course not. But they don't match the LR4 in specs. And for the added length on the outside, you get worse space on the inside and the system for flattening/moving/removing the seats is ancient. A number of other vehicle makers have found far more clever and useful means of doing away with the seats when you don't want them.
