I really enjoy YJ's. Thats a personal choice. I also dont give two shit's about bouncy rides vs soft, plush rides. Ive had people say my Jeeps are bouncy or jostling. One a Tj, the other a JKU. Either way, Its never going to be very quiet (w a hardtop, mine is respectable) or Cadillac smooth. You'd be surprised what some people expect.
Some Jeeps also vary how they ride, primarily when lifted, and how. All stated, yes, a TJ will ride better. But some people prefer the YJ, still.
You'll need to test drive both. Find one F/S (best at a lot - though YJ's are quite rare now) and see which you prefer. I personally would take either. Especially if equipped with AC. And IDGAF what anyone says.....AC is a damn nice option to have on a Jeep, nonmatter the year. Thats my personal opinion.
