All jeeps run the same chrysler/daimler electronics.
I own an 08 grand cherokee, and it's basically a minivan with a good driveline, but typical chrysler electronics glitches (M-class was notorious for electronics problems), a front suspension that looks lock, stock, and barrel like a honda accord, and thin sheet metal. I do off-road mine some, and it DOES have generous suspension travel, but it is not as solid, in my opinion, than previous generations. The hood and one back door have never quite lined up correctly, right off the new car lot. I think the mechanicals will be fine, but am prepared for the same electronic woes that I faced in my aging town and country.
The wrangler still has a lot of its original pedigree, however. The 3.8 is a reliable engine, the frame is SOLID and it WILL walk right up the side of a mountain. It has similar electronics, however it appears better protected, better sealed, and hopefully will handle corrosion and wire rot better than other daimler products, just because it's packaged with more care.
I have owned 2 jeeps and like them for what they are. Keep in mind that the 4.0 ZJs and WJ's (grands gen 1 and 2) had reliable drivelines but nickel-and-dimed folks to death with creappy hvac problems of different sorts, various electronics woes, etc.
The 2011+ GC is a beautiful vehicle for what it is, tho it is complex, no solid axle, and to me is more of a mall crawler. For the money, you start to get a lot of different competition. The chrysler 3.6 should be a remarkable engine and is mated to a solid transmission.
That said, I'll prolly never go for one. I like solid axles, and I do tow--- and 4wd with 4 wheel independent suspension introduces 8 rubber boots that age, crack, and require replacement, bushing wear on all those suspension links, etc.. So.... in my opinion, if y'all are interested in a wrangler, do it, they are great. the other offerings.... meh kinda lukewarm.
also keep in mind, folks buy these things then cry about mpg. The wrangler is FUN and with the manual you can actually get decent mpg... and even when you don't, people tend to fall in love with them and the price at the pump is less of an emotional issue. The grands are more subdued, and if you use the a/c and crawl in traffic you will get less than sticker. 14-16 seems pretty typical real-world, and that's hard on folks. There's a lot of used cherokees out there.
my $0.02. Take it FWIW.

Honestly if you look at the prices of older jeeps you will see people want them and people selling them know that.
