Two doors can be very hard on the hinges and the doors too. They tend to tear away from the frame and you'll see a lot of 2 door XJ's with either bad doors or repaired doors. 97-up models may be better, because they changed the hinge design. This can be repaired, and also can be avoided somewhat by making sure that the door check straps are in perfect condition and not flinging the door open. What happens is that the doors are just too heavy for the check straps to restrain, so when you open the door, either the strap pulls too far or the frame of the door itself bends outward over time, and the strap becomes effectively too long. When that happens, the door hits a second stop in the hinge itself, and then it pulls the rear edge of the hinge out of the body.
On my stepson's 93 2-door, I repaired the hinge, then shortened the check straps by welding the hole shut and redrilling about 3/16 inch further back. That saved the hinges from further damage, but now the door skin is coming loose from the door itself!
One advantage of 2-doors is that they give better side visibility if you're tall.
Here in the rust belt, it seems that the bottoms of the 2-door quarter panels are especially vulnerable.
