The Ford Mustang is a prestigious sports car with

a sophisticated cabin and razor-sharp handling, 

two areas that easily surpass Challengers. The finest 760hp Mustang is one of the

 few that closely matches the Challenger SRT variant. 

 Use Dodge to get more second row rooms and a larger trunk. 

Therefore, if you want to prioritize these things,

buy Challenger. For a more rounded muscle car,

 the Mustang is not defeated.
