I own and wheel a 2.5l/auto. I don't daily drive it and wouldn't recommend it unless you like to not accelerate. It will move under its own power, but I move faster in my Forenza.
The difference in cost is easily absorbed in the multiple years of ownership. Gas mileage is nearly the same, though with a gas tank mod on the 4banger, you do go farther in a tank full. Resale is also greater between nearly stock TJ with 6cyl vs 4cyl. I wouldn't want to daily drive my 97 2.5l/auto TJ.
I do have another 97 TJ but with a 6cyl/auto. It is stock except for the 30s. I prefer to drive that than the 4cyl. But I prefer to drive the Forenza than either of those. The red TJ (6 cyl) has full doors. Really no room on the left side. The blue TJ (4 cyl) has half doors and I prefer that more, but the driving pleasure is not there with acceleration. The Forenza does sit low on the ground, but I can atleast hear the radio, accelerate, and change lanes with drastic manuevering to get around other drivers.
