If you want to learn about LC's, I recommend checking out
www.ih8mud.com , a dedicated LC site. I own a '96 FZJ-80 and love it. It's slightly bigger than the 4Runner both in length and width and interior space. It's a very solid rig, and it has a lot more power than I'm used to with 22R and 22RE's, and 3.slow V6's. Durability-wise, the 80 is quite strong and dependable, arguably the best. It is heavy, safe, has 3 row seating, full time 4wheel drive, optional front and rear selectable lockers, easy to lift, and overall nice to drive. Yes, the fuel economy isn't that great, but I'll take paying a known amount more in gas versus paying an unknown amount more from risk of repairs on lesser quality vehicles. My 80 is stock with exception of a brushguard. I get about 15-16 in the summer and 13 in the winter on oxygenated fuel. It's not worth it for me to sell the 80 only to buy something that may only get a few mpg more than what I have now.
I've owned a 1990 4Runner for about 10 years and love it, but I can definately feel a quality difference between it and the 80. Afterall, the 80 was Toyota's flagship SUV (and still is).
I drove my other 4Runner the other day, a 1995, and I forgot how it's like to drive a rear wheel drive SUV becuase I'm so used to the full time 4 wheel drive in the 80. I didn't shift the 4Runner into 4WD because it didn't seem "that bad" out, but I spun the tires several times and the rear end wanted to spin around. Our winters can be pretty harsh and I don't know if I will ever go back to part-time 4WD. We even sold my wife's beloved Camry for an AWD Subaru Outback.
The Land Cruiser (and my 1996 FZJ-80) get two thumbs up in my book.
