Unless you plan on shuttling soccer teams around all the time, I'd say no, they aren't worth it.
A lot of factors will play into it: How many kids do you have? How often do you find yourself "shuffling" people around to other vehicles ("We have to take 2 cars"). How often do you find yourself packing a lot of stuff (traveling, camping, etc).
Personally, I prefer the cargo space, and I love my cargo deck. I can fit 4 adults and the car seat in mine with no 3rd row, and I've never wished I had another row. All in what you need! Hope that helps.
