I personally really like the 12+ chargers. There's a woman at my work that has one. Sxt but has all the R/T appearance options, as well as Nav. No leather/sunroof which would be a potential deal breaker to me.
Honestly I don't think an R/T would be too bad as a DD. Gas mileage isn't as good as the V6 but it's better than DDing an SRT8.
But all that aside, I'd buy a 300 over a charger 100% of the time
