The Explorer was at the top of my shopping list...until I drove one. It has very strange ergonomics. It feels very much like driving a minivan. The Durango was far more satisfying from the driver's seat, so that's what I bought. The fantastic exhaust rumble from the Hemi in the R/T is a great bonus.
Both the Pilot and the Highlander were cut from my list because both mandated captains chairs in the middle row for the top trim level. I have 3 kids and I need the middle bench, so goodbye Honda and Toyota. The new Pilot looks like a blob anyway.
I don't care for the Korean brands. The GM offerings didn't do it for me. Durango R/T won. I've been very happy with it.
The new CX-9 wasn't out yet and the wife had already waited a year and wasn't willing to wait any longer. I would probably choose the Durango anyway given the honest V8 power, despite the MPG penalty. To be honest I worry about these highly-complex turbo 4 engines powering these large vehicles. What will the long-term longevity be? I plan to drive the vehicle for a decade, just like I did my '04 Pilot. I also wanted tow capacity for boat and RV rentals (I own neither) and the Durango tows 7400 lbs.
The new CX-9 is a beautiful package but honestly seems to be targeting a different market than the standard 3-row SUV offerings. Seems much more a AWD wagon with a third row for cruising suburbia. Not that there's anything wrong with that (I love wagons) but some of us still want/need an actual SUV-type vehicle and the CX-9 ain't it.
I love Mazdas though.
