What new gen Challenger is best and Why?

I have a 2009 5.7 R/T stripe deleted, 6 speed manual transmission zero options. Fast, smooth, quiet, 28 mpg at 70 mph highway. Only suggestion is to get the fix for that Idiot skip shift that locks you out of 2nd gear at a certain rpm. My wife has a 2012 Charger R/T 5.7 with the automatic transmission. Great highway car, plenty fast, 30+ mpg highway. I'd say take your pick. Not sure I'd get a 6 though.
