I love my Jeep. I have a 2012 JKUR that gets at least 80 miles a week off road. It has about 35,000 miles on it, and is by far the most reliable vehicle I have ever had from Jeep. They are better now than they ever were.
I live in Dubai, and the pentastar Jeeps are the king of the offroad scene. But its all about power-to-weight ratio and purely 1-2 day trips. The Nissan's are becoming problematic. I see more breakdowns from X-Terras and patrols than any other brand in the desert. That doesn't really get Land Rover off the hook though, because in the last 12 months, I've only seen 1 Landy out there. Must be 50,000 of them rolling around Dubai and Abu Dhabi, but they don't get out much.
FJ Cruisers, Prados, Land Cruisers (100 series, 80 series, 70 series), Fortuners, and the ever present Hilux are out in force. They always keep up and they never break down. If I was going to be out of cell phone coverage for days at a time, it would be in a Hilux. I love my Jeep, but the quality comparison between a Jeep and a Hilux is all in Toyota's favor. I would feel much more comfortable on an extended remote expedition in a bone stock, base model, Hilux (2014 drives out in Dubai from $17,500 about $10,000 less than a JK sport) than anything from AEV.
