The JK and JL do not wheel similarly to the TJ and CJ at all and the TJ and CJ do not have the highway road holding of the JK/JL either.

They are entirely different classes of vehicle where as the TJ/YJ/CJ are very similar save some chassis and suspension differences. Heck, you can install the CJ dash into a YJ, and probably could do that to a TJ too if you got rid of the air bags.

As for off road performance, a TJ on 33's will destroy a JK-U on 37's on the Rubicon. That's not really up for debate as I've compared them extensively in person. The biggest eye-opener was crossing the Rubicon Trail in a stock JK-Unlimited Rubicon on stock tires and we also had JKU's on 35s and 37s', heavily modified, and the lone TJ on 33's with a mild OME lift crawled right around them.

Now the TJ was trailed to the trailhead in a 2500HD pickup because it sucks so bad on the highway, even lightly modded, it still can't road-hold at 70mph like a JK can, and the JK's aren't exactly known for their handling either.
