I LOVE our Jeep! It's our 3rd JK. We bought a 2 door and just couldn't wrestle the kids in and out of the back. The 4 door was fine. The one we have now is our 2nd four door. Fully loaded Ruby with MW3 package plus pretty much every possible dealer installed ARB option the original owner could check the box for - LOL! I'm using it for work right now. Surprisingly comfortable vehicle and sits high enough that I can really get a good view in traffic. We do wheel with it and it is absolutely impressive off-road.
If you are looking at a 2018, I think they are selling the JK as a 2018 along side the new JL. If the price is the same - buy the JL. Otherwise, just buy a year or two old JK. Best buys are the used ones with all the extra add-ons because you buy the add-ons for around half what the previous owner paid for them (winch, racks, sliders, etc).
