Yeah it was definitely more the CJ5s than 7's for sure. The CJ5 could be downright scary to drive. Super narrow axles, tiny overall size, very short wheelbase, not much else to it. 7's were a lot better, they almost feel like a YJ to drive anyways. But spreading the springs apart, wider YJ axles (even the CJ wide tracks were a few inches shorter than YJ IIRC), adding sway bars on every one (only some CJs had them) and apparently adding the track bars all seemed to help some. The CJs had better steering so no track bar on them didn't hurt the steering feel, unlike the YJ.
On the flip side, my YJ with OME suspension was scary without a sway bar so I had to add one back. The springs are so soft that you feel like you're going to roll just taking a slight curve in the road at 35 mph.
