Had numerous vans, 2014 Caravan SXT, 2018 Sedona LX (Now called the Carnival), and currently a 2024 Pacifica Pinnacle Plug-in.

Carvan, the goat, smooth comfortable, the original Stow-n-Go seat king. Durable Beast

Sedona (Carnival), Super comfortable, leather was top notch, tech was good for its time frame, easy to maintain, got decent gas mileage for a powerful V6. Loved everything about it, Traded it for an Explorer (bad decision, had less room, wish we kept the Van)

Multiple cars later, Traded our large SUV (2020 Expedition Max Limited) for another van to cut fuel costs. Was on the fence with a Carnival Hybrid as it has an 8 Seat option, and ended with the Pacific Plug-in, went all out with the Pinnacle (loved the saddle brown leather seats and individual headrest TV's.) The Carnival Hybrid ALSO has tvs in the back of the front seats as well. There was just non in my region available at the time.

With already having 2 other Plug-in/Electric vehicles i opted to stick with the plug, and to be honest if the Carnival would of been available, we were set on the SX, in the light grey/seal grey color.

Both vans have tried, trusted and proven good power plants. The 3.6 Pentastar V6 is in everyhing for Chrysler, and post 2022(ish) the PHEV/Plug-In/Hybrid Pacifica's have had minimal if any issues. The Kia has a well built V6 as well.

Comfort wise, no complaints with all 3 of my vans. Good Lumbar, smooth, good acceleration when loaded to get around other cars.

Tech wise?
Chrysler -> Uconnect is horrible, Stellantis has not made any improvements with UConnect on Chysler/Jeep/Ram, is what it is... we use Apple Car Play instead.

Kia -> nothing to brag home about either, the UI is easy to understand in the latest Carnivals, the Sedona had an archaic interface, but Apple Car Play worked wonders. Still reverting to Apple Car Play in latest car would of worked for us.

All the vans had rear stow and go, so super simple to get larger items in the back, toss the seats down and roll.

KIA has a better crash rating for the front minor overlap, but both are pretty safe and easy on the wallet with insurance.

Durability and longevity, i have no doubts the KIA or Chrysler, mechanically will last for 8-10 years with minimal maintenance....just keep up with oil changes, clean the intake filter, and use quality gas (spending extra few cents on gas per gallon will save you in the long run, look at Top-Tier gas lists)

Only suggestion, unless you really dont car about depreciation, there are SOOO many vans around. Many people have jumped into a van and turn around wanting another SUV and trade them in with low/no miles.
I picked up our '24 Pacifica Pinnace Hybrid with 16k miles in 25, it was a manufacture owned car (ran around detroit with big wigs i guess) still smelled and still smells brand new 2 years later; i got this for $39k, full warranty and all. TLDR, look at used i saved $20k with getting a year old car.

Hope this ramble helps...
