Pretty much what doop said. TJs are great, but much overpriced almost all of the time. Half of them are stock and you’ll want to spend a hell of a lot modding them. The other half are already half ass modded pieces of garbage that you’ll spend money undoing the garbage first before you can get to the stuff you actually want to do.
YJs are mostly in poor shape so unless you find a real clean one, expect some work. Even on the clean ones, expect some work. They’re all super old and none are perfect anymore.
YJ quirks are the vacuum 4wd system which you can get rid of in a few different ways. Dana 35 rear axle is semi weak depending on what you plan to do, YJ steering sucks, and gets worse once the jeep is lifted. You have to expect a rough ride and very few to no amenities.
For the good, they are fun to drive, can look great, and are unique. The ride quality can be improved and most quirks can be solved relatively easily. If you can find a good shape YJ for a decent price, go for it. Stroker would be fun, I would want to know the details on it before I bought the Jeep. Where it came from, how long it’s been in there, how many miles. Lots of stroker recipes and some are better than others. Longevity is the main reason I haven’t jumped on a stroker. Some can last a long time, some don’t. The inconsistent reliability is why I haven’t jumped on it. I’m sure one would be a blast to drive though.
It’s not a must but I would stick to 91-95 if you can. They came from the factory a lot more modern than their older brothers. YJs evolved quite a bit over the years, the best year hands down was a 95 but all of 91-95 are good. 92+ is all electronic backlit gauges, 94+ is external slave cylinder on the manuals. 91+ is all MPFI.
