The durango is if you need the extra row/space and it drives like an suv. It does however have updated tech like the gauges, display, etc etc
The trackhawk feels more like a car than the durango but feels slower from a roll because of the weight + height.
Charger, useless from a dig on the street without drag radials, can survive non harsh winters on a winter set of tires but not ideal. Handles the best of the 3.
It really depends on your needs, the example I use is the durango is for your wife/gf or long trips or if you need 6 seats, the trackhawk is if you have brutal winters and need awd, and the charger is a good weather vehicle.
All have their pros and cons, the trackhawk won't get beat at a stoplight and the durango probably won't either, the charger will, on the highway charger is king.
Just my opinion, you have to sit in them and get a feel for what best suits you.
