So just how good was the A-Body back in its day?

My second car was a 71 challenger.
My forth car was 73 duster, I owned both of them at the same time.
The duster was all around better driver, much more agile just a better all around car.
The duster did most of the daily driving needs, the challenger ended up just being a second car, I actually sold the challenger in the 90's when the price of mucle cars went thru the roof, but kept the duster.
