I drove the CX7, CX9, Edge, and the Murano when i was test driving crossovers last year. Here are the impressions of each vehicle.
Ford Edge: drove this one 1st. It had great power, felt good driving. the day we drove this thing was a windy day on the interstate, and it still drove good.
CX7: seemed to really have power,but just didn't have that refined feel to me. The interior was pretty plane.
CX9: Was very nice inside, it had a sluggish feel to me, and seemed to feel like i was driving a top heavy tank.
Murano: seemed to feel like a car when we drove it. the back up camera was nice addition as well. had decent power, didn't care for the dash layout. Liked the keyless ignition system.
I wound up buying the edge, and haven't regretted it once. Each vehicle we drove was loaded, and all an all, im still glad we got the edge.
Only features i would like to have had was the keyless ignition, and the backup camera.
