This is all just personal preference. I have owned both and they are both amazing cars. However, the only reason why I got a challenger at that time was because I couldn't find/get a 'Cuda. I personally feel like the 'Cuda is a more novelty/badass e-body, whereas the challenger is a more common/well known muscle car. Basically I'd Put the 'Cuda up there with cars like Boss 429s which you never see, ever, and Challengers with Shelby Mustangs which are more common and more well known by people outside of the muscle car club. All in all, both amazing cars, but the 'Cuda has its own place in automotive history as the quintessential muscle car. There's a reason why Cuda's with the same drivetrain and options typically sell for more $ than Challengers.
