I've not seen any videos comparing off roading to the LR5 vs the older models.

I did see one where the LR5 lost to a jeep rubicon and a few others.

The 21" rims seem to be an issue off road, not much rubber on the sidewalls.

I though some LR3s had 17" rims, mine has 19" and people said those are too thin for off road and now they got 21". If they keep going there will be zero rubber on the side wall. They are not race cars so I don't get why they keep making the rims taller and taller.
