I've owned a 2010 Challenger RT Classic since it was brand new. I owned and restored a 70 Challenger in the late 80's and had it about 15 years. When the late model ones came out, I had to have one.
Taking a step back and trying to be unbiased, the Challenger is the largest and heaviest. This works for it and against. It has the most room inside, a very roomy trunk, but that works against it from the handeling point of view. On paper, depending on what you get, the Mustang and Camaro out perform the Dodge. All of them are great performers though.Went for a ride in my neighbors 2016 hellcat "HOLY JESUS"to much power for us..LOL
The Challenger has a little of the feeling of looking out gun slits, but the Camaro is much worse and the Mustang isn't much better. They all suck looking straight back but back up cameras come on a lot of them.
Looks? If you are into the retro look, the Challenger wins hands down. In my opinion, the best looking of the three by far, with the Mustang looking good to me also. No insult to Camaro owners but they just haven't grown on me.
The Scat Pak is a great buy, less than the SRT but very close in performance. If you want a better cruiser that rides a little better, look at an RT. I own an RT but would much rather have a 392 car.
