The best feature? The only thing you lose is the ability to fold down the middle seat, but you can still remove it if you need to haul something large. We had one for 3 years and needed to take the seats out 3/4 different times.
It's really the defining feature of the Chrysler vans compared to the others, the ability to go from "all seats in van" to "flat empty van" without removing the seats is quite a nice convenience.
And I don't know if you can even get the hybrid in the 8 seat setup, and it's more than $10k more than a somewhat similar Kia.
