I had a '20 (early 2019 build, so one of the very first) Gladiator Rubicon that had everything except the forward camera. Transmission went out at 14k miles, bad pump. That was the only issue i had in 75k miles. At 3.5 years I had to replace the batteries, 1 went and the other went a month later. I towed my airstream, car trailer and did a bunch of off-roading, etc. I loved it, and I really used it like a truck. It did everything well without being a PITA to drive daily like a full size truck. I had a 1/2 ton Chevy previously and the Gladiator was way easier to live with every day, especially if you need to park on the street, park it in parking lots or parking garages often. I had swapped on mojave shocks which fixed the lazy shock damping, added a winch and soft top for the bed, otherwise stock, got 18.5mpg average.
However, my kids are getting bigger, my mom moved next door and I have two dogs - we found ourselves frequently taking multiple vehicles as we could not all fit comfortably. I ended up buying a Defender 130 to solve that - seats 8, 7 adults comfortably, can tow more than the Gladiator and has higher payload. I kept the Jeep but ended up trading it for a 4xe around a month ago as it was doing mostly short trips and no towing/hauling, so the 4xe was just a better fit.
By comparison, the D130 gets 20mpg. 4xe gets 20mpg in hybrid.
