If you look at nothing else, just look at the retained value after 5 years of the GC vs the LC/LX platforms....
There really is a different quality culture in Japan, and you have to remember that the LX/LC are the flagship platform of one of the best auto manufacturers in the world. They made small refinements to all landcruiser series every year without any major design changes for ~9 years usually.
Jeep sells off of old reputations and new-fangled gadgetry. They constantly have to change designs to keep buyers interested and to attempt to make it possible to stomach a new, $50,000 Grand cherokee (that will be worth $30,000 in 2 years).
I will say that of the three landcruisers I have owned at this point, none have ever failed me in any way, and all I have done is basic brakes, oil, and diff fluids (only when needed and none have used oil). Also, my first was a 1989 FJ62 with 200,000 original miles and it didn't leak a drop of anything on our clean concrete floor. Coming from several older Jeeps and Mopars of different kinds, they always had leaks and my wife wouldnt let me park them in our new clean garage. My ex boss has a 2013 GC with a V6 and although he likes it overall, it has been in the shop for transmission issues and weird engine drive by wire surging issues as well (this disables his cruise control and turns on a code). He told me several times that he wanted to sell or trade it but was already so far upside down that he just couldn't bring himself to take the bad bath.
One great thing about buying these 100 series landcruisers used is that they have already taken the drop in value from when they were brand new, and the used buyer can really get a great deal on a lot of quality engineering for a very affordable price. I know that I can literally turn around and sell my 2006 Thundercloud 100 series for more than I paid for it 2 years and 35,000 miles ago.... try that with a Heep. the used values are just amazing on these rigs if kept in good condition.
See if the rigs you are looking at have already had their timing belts done or not, and check for maintenance receipts/ records for oil changes and diff services and brake jobs.
As a side note, I have a buddy who never listened to me when I told him to change the timing belt on his 2007 Toyota Tundra 4.7L, it finally broke on him and didn't hurt the engine at all thankfully.... it broke at 226,000 miles on the original belt.....
