To answer the question, I mention the main points and compare a late CJ to an early YJ (91 on had fuel injection and a boxed rear roll bar).
Frame: YJ is 4 inches wider
Engine/ carb: same
tranny: both medium to light strength
t case: CJ is all gear and YJ is chain driven
Front axle: CJ has locking hubs (diff doesn't spin in 2wd) and YJ has no lock outs (diff spins while moving)
Rear axle: CJ had a 2 piece hub (most late CJ) and YJ had a C clip (most) CJ has 5 on 5.5 bolt pattern while YJ is 5 on 4.5
Springs: YJs are a tad longer and wider in front (yj also sits a tad lower)(CJ has more articulation)
Body: dashes are differnt, tailgate and hardtops are different, YJ has side mirrors on doors (same doors), gas cap on opp side, CJ windshield folds down in seconds, YJ has "Bars" bolted in, 85 on had fold n tumble rear seat on both, ETC.
Both will have a sway bar and have similar handling characteristics while the yj is a tad more road friendly and less off road ability and the CJ is opposite. They can interchange about 75 to 80 percent of thier parts. The problem is that a lot of folks try to compare a new Wrangler to the older style of CJ (pre 76) and there is a huge differnce there.

YJ's have galvanized tubs, CJ's don't. Thats why most guys put YJ tubs on their CJ's

Just had to throw in that a LOT of YJ stuff can be used on a CJ, you just have to know which. My CJ has a YJ hardtop, fits great, but I have to mod the rear of the top where the hatch meets the tailgate, due to YJs having the side-swing tailgate, and CJs having the drop down. I have to go inside and open my tailgate to open the hatch..

CJ vs. YJ

First of all, right on Ed ( Only in a CJ),

I have a CJ with a Wrangler tub and love it. I converted my YJ tub's tailgate to look like a CJ and moved the fuel filler to CJ style. It's easier to put an AMC v8 in a CJ frame since the mounts bolt up. The wrangler has welded in mounts and some trial and error is needed IF you are going to run some big HP. If you are it's considered way cooler to use an AMC V* vs. anything else.

CJ' S RULE!!!!!!!!!!!!!!!!!!!!!!!!

SPEED COSTS MONEY: HOW FAST DO YOU WANT TO GO?

Jersey Joe, I liked your post so much I had to read it twice!!

I'm also putting in a YJ airbox in my CJ , but there's an "extra" flap in the venting that I'm not sure of the reason for. it seems to have a see-thru tube that may close/open it with vacuum. I don't believe that was on the CJ one. I'll just keep it wired open til I can figure out how to use it.
