In a simple word - and JMHO - NO. You are going to have 50 people reply, get 85 opinions from them, and every one of them will claim their way is the only way. Good luck with that. So this is what you just did, opened a big can of worms.
You are a big portion of the answer. What works for me may not be for you. There is a sliding scale in there, things to be considered on this scale is not just reliability..... but your mechanical ability, parts availability, and just what it is you want to do with it. MY OPINION: the 2012+ JK-JKU is perhaps the place to be right now.
YJs are nice but not as capable and need a lot of work and mods to get that capable. TJs are nice but getting kind of old. Depending on where it was driven and how it was cared for it may require extensive repairs, perhaps even a full frame replacement. The stock 4.0 I-6 is a steady engine with possibilities, but it isn't anything to write home about unless you do a lot to it. The LJ version is one to have if you can find one in good condition and can afford it.
The early JK-JKUs had the 3.8 liter V-6. There has been much written and said about that engine. Somewhere in 2012 the JK/JKU platform moved to the 3.6 liter V-6 Pentastar. That engine has it's haters and detractors. But if you consider that it has now been in production for 12+ years and how many vehicles use the engine, maybe the reliability isn't so bad after all. I take all complaints with a grain of salt. You will always hear the complainers because they are loud. They always claim proper maintenance was done religiously, only the best oils were used and the vehicle was never mis-treated. We've all heard recently of the Pentastar that had over 600,000 miles on it before a rebuild was needed. I know several that are over 300,000 and still running. There are some weak spots in the 2012+JK-JKU. Show me a vehicle that is perfect.
The JL-JLUs have their own issues. I know several early JLs that had issues. I also know several that are used as Overlanders and are not having issues. The fact that you can buy a JL-JLU built up and on 35s now is enticing. But unless you can special order a JL-JLU, you will be getting stuck with stuff that I would not have. There is no way I would own the 4XE. Way too many complaints about the battery. There is no way I'd want the E-Torque, again too many issues. And I got that warning from the local dealer mechanic, he is the guy who sees them come in on warranty.
The JTs have their own issues. I've not followed them closely because they just will not work for me. My JKU-R Hard Rock has a 6-inch Overland Lift on 35s, and I have scars on the bottom of my rear bumper. The rear-end of the JTs sticks out like a fat chick's booty. I can only imagine how that would work for me. There are about 10 JTs in the club. Two of them have issues, one is a clutch problem that the dealer has been sitting on for 10 months.
Bottom line is this. No matter what you consider, someone is going to tell you it is the best, and someone is going to tell you it is the worst. In the end you are going to need to form your own opinion and go with your best guess.
Me personally, my 2015 JKU-R Hard Rock has 73,000 miles on it. It is a TOY. All of those miles are off-road miles, or road miles on the way to off-road miles. No mall-crawling, no daily driving, no grocery getting. Everything is working perfectly. Stock 3.6-liter V-6 engine. Stock 5-speed Automatic Transmission. Stock 4:1 Transfer Case. Stock Dana-44 Axles F and R with stock lockers, regeared to 4.88:1. Front axle trussed and gusseted. Dyna-Trac big brake kit F and R and Ram 2500 Master Cylinder (I have brakes for days but I overland a trailer). Lift is AEV 4.5-inch S/C kit with AEV high capacity Overland Springs (6-inches lift realized). I have skid plates, diff-skids and lower control arm mount armor. All things considered, my only fear of this build is wearing out the engine. If that happens, I'll likely replace it with a Jasper and keep rolling.
That is my opinion..... FWIW. JKU-R is where I want to stay.
