Wow, a lot of non-Jeep friends in this thread :-)
I had two Jeeps for 16 years now (a YJ in the 90s and -still have- a JK Unlimited since 2011) and both were/are super reliable. In the JKU i had to change the starter at 140k+ last year, and I am at 151k now - no other problems at all, just regular maintenance that you can do in your garage.
Now that the prices are out for the Gladiator, I think they are within reason/comparable to the competition, for example the Rubicon is about 1k-ish over the Tacoma TRD, and has more features, such as the removable top (and I don't want to start a flame war here, YMMV). Yes, a bit more but not too much.
I am looking forward to driving one later this quarter when they actually arrive on my dealer lot, and will look for a Sport S with the max tow package. That seems to be a good deal. I don't need a Rubicon here in VA (my JK is a Sport S as well and has served me well even without the Dana 44 and red stickers), and rather spend additional money for good tires, etc if needed.
I definitely recommend to drive it stock for quite some time to figure out what you actually "need" (want). The major changes to my JK came at about 35k on the clock after a cross-country trip with our teardrop trailer.
Don't buy into the marketing hype - Jeeps are very capable stock.
