NEW 2015 Challenger
I've driven both the latest mustangs and the 2013 challengers a lot (over 1000 miles on both) The mustang was more fun to toss around in the hills in California but the challenger was a better highway car.
Honestly though, The Challenger needs a new look and not some makeup. I know there is no budget and they need a clean slate chassis but it's really time if they want to stay competitive in the pony car game.
