I've had 3 Power Wagons for work, each one bought new and driven to just over 100K miles. It is a good choice for me as it has good skidplates, a winch, and low ring and pinion. All of my sway bar disconnects have broken, as have the lockers, as well as countless other things...in all of the rigs. Every time I fix them they break again, thus I've stopped fixing them and just drive around with no lockers (nor sway bar disconnect) and a flashing warning light covered in electrical tape.
My newest PW only went about 1K miles before the wheel speed sensors went wonky, causing total VSC freak out at highway speeds...very fun. I also strongly dislike the new transmission as it prevents me from manually shifting, except by the funny little switch on the stalk (slow to respond).
The PW is better on the highway, especially with the new transmission, but the 80 runs circles around it off-road or on rough roads. The PW has pretty bad visibility as well and is rather large (especially the new one), which makes driving an 80 on semi-technical trails way easier...and thus significantly less tiring.
When not at work I drive my 80, and smile every time I get in it. When I compare it (97 with 130K) to my '13 Power Wagon (15Kish) it is night and day what a superior vehicle it is. The build quality is immeasurably better.
No comparison....IMHO.
