Not sure if you've seen them side by side, but Defender was the king of off-road capability in the 80s and 90s. While YJ was rolling on leaf springs until 95, Defender had been on coils since 1983. Even when the TJ came out in 97, the Defender's longer forged control arms were far superior to the short little stamped arms found on the TJ. It wasn't until the JK and LR's pivot to London chic cars that Jeep pulled ahead.LR copied the Wrangler decades ago- the first one even rode on a Jeep chassis. They have never measured up in off-roading although, admittedly they have rode nicer, but even that is now being challenged with the much improved driving dynamics of the Wrangler.
