I have never used any BFG tires, so I can't compare I'm afraid. I hear great things about them from fellow LR club members, and they do look great (both the original KO and the new ones.) I think the LT285/60R18 Nitto Terra G2s (E-load) I have are excellent all-around A/T tires if you want traction and nearly bullet-proof protection from sidewall damage off road but competent and comfortable tires on pavement, which is where is spend 99% of my time, unfortunately.

They have served me well over every terrain and conditions except mud, snow and ice - never had the opportunity - and I will definitely be getting another set soon: mine are chewed up even worse than yours, but I do have nearly 60K miles on them and I off-road them pretty regularly and heavily, so I can't complain. There is still quite a bit of meat on them, as you can see. With a lesser tire I am sure I'd have slashed a few sidewalls by now. They are heavy and a bit noisy, that's all. But so are the BFGs and most LT / E-load tires. I figured if it ain't broke...
These are the types of trails here on the West that, slowly but surely, will chew through your tires and give your sidewalls grief (just came back from a fantastic few days up in the Sierra with some friends):
Depending on where you live, your needs may be different. For instance, for rough / snowy winter conditions, these Nittos probably wouldn't be my first choice.
NASdiesel, specs and clearances for brakes, wheels and tires have never changed for the LR4. Whatever worked for a 2010 also works for a 2016.
