The JK is a recreational 4x4 built for weekend duty and that's it. The Defender is a commercial 4x4 built for professionals who run off road for their jobs 24/7. Also, the design on the JK is not particularly good for a 4x4. Yes, the suspension flexes pretty well and the Rubi has lockers, but the rest of the design is poor and it's that way because it's compromised for on road performance where most new Jeeps spend most of their time. For example, Look underneath the JK and you'll see that the drivetrain is set very low in the chassis for on road stability. The short wheelbase can get by with that to a degree, but the long wheelbase really drags its undercarriage off road on stock size tires. To overcome this you have to put really big tires on the Jeep which then means that you have to beef the rest of the drivetrain up because now that is underrated for the tire size. This even goes for the Rubi with D44's which are often completely rebuilt or replaced completely due to the weak front end parts installed from the factory. This low hanging undercarriage has been a problem for Jeeps going way back. My friend is currently raising the drivetrain of his YJ to get rid of that low hanging trans/tc crossmember. My CJ5 had that too. Look under a pre IFS/IRS Land Rover and you will see that the designers have everything tucked way up into the chassis for protection and clearance the way it should be for a 4x4. Stock size tires or a size or two larger are all you need to go some very difficult places, without lockers. Add to that stock 3.32 low range gear driven transfer case, full-floating axles front and rear, stock long-arm suspension, etc. and you have a much better designed 4x4 than any Jeep. The Defender 110 even comes with a full floating Dana 60 in the rear from the factory. The frame is fully boxed and very strong. The JK is nowhere close to the payload of the Defender either. It's in a whole other class so can't be compared in truth. The only reason the JK is compared at all in my opinion is that it looks the part: flat panels, exposed door hinges, utilitarian air about it, etc. I think if you're going to compare anything Jeep to the Defender it would have to be the J8 which is truly built to commercial specs like the Defender, Land Cruiser, Patrol, Gelandewagen, and vehicles like that which are also meant for full time professional use off road.
