Simply making it through a trail and making it through without body damage, carnage, winching, swearing, anxiety, etc. are COMPLETELY different things. Just because you can ride a motorcycle through a blizzard doesn't mean it's the same experience as going through with a Subaru on snow tires, so your argument is not logical. I've owned roughly the same number of Jeeps as Toyotas, and I like them equally for different reasons. You are entitled to whatever opinion you want, but the FJ or just about any other vehicle which costs less than $50k new is not as good off road stock as a Rubicon. There is so much objective reporting on the topic from magazines, op eds, user reviews, etc. it's really not even a defensible position. I haven't seen anyone in this thread be a Jeep fan boy whatsoever, but it's clear you have bias towards the Toyota and that is completely fine.
As for the Africa, I would be one of those people who would love to have one, and I think with a pop top similar what Ursa Minor does would be the ultimate overlanding vehicle. My only concern would be the price considering a loaded JKUR is already in the upper $40k range, but I am sure anything Jeep puts out for sale will be a hit with a lot of people. It seems Jeep has been moving in the right direction with the Wrangler since it offered the Rubicon in 2002, and I have no doubt they will continue to come up with cool stuff (albeit more slowly than we would like) in the future. The fact you can buy ready to go Dana 60s at your local dealership along with high top fender, lifts and beadlocks is mind blowing considering how back in the 90s if you put a sticker on your Jeep they would decline warranty coverage for "modification" it seemed.
