I went from a '96 ZJ Limited to a '99 WJ Limited. Honestly, I liked the ZJ better.
WJ: Looks nicer (IMO) More power (OHC 4.7L vs. 5.2L) Full size spare fits under the rear floor.
ZJ: Rode and handled better. Better gas mileage. Seats were more comfortable. Better in the snow ("varilock" in the WJ transfer case is crap.) No dual-zone HVAC (who cares? not worth the repairs!!) Costs less. More reliable. All the same luxury gadgets as the WJ.
Not that the WJ is a bad car, I just expect newer models to be substantially better than the ones they replace - and it isn't.
Go test drive a few.
