You'll find there are alot more mustang owners here than you'd expect. Some of us gave up a faster mustang for the RT with no regrets, I sold my 2004 SVT Cobra for my 2010 challenger RT, and am still pleased with the purchase. I would however have opted for the 392 if it had been available back then, but the 5.7 actually performs quite well. It is a different type of ride than the mustang, a lot smoother, mine doesn't have the track pack so it feels a little soft, but when pushed the challenger holds to the road great, does not have excessive body roll, and has more than enough power to get yourself in trouble with. You'll find the Hemi tends to like being wound up a little higher than the mustang does. Its a world of difference driving a challenger at 80 vs a mustang GT at the same speed. And you'll find cruising steady speeds pretty much feel the same at 70 as they do at 100 without noticing any strain. Dangerous for those of us on longer trips as you tend to speed up over time. first time i've ever been caught over 90 was this year, and I'd been driving it for 4 years.
Unless you want more road feel, to notice every pebble you run over, enjoy feeling a little cramped with 4 people in the car, you won't regret getting a challenger at least over a GT, a shelby may be a different story, haven't tried one of those yet. Personally I'm thinking of either getting a used boss or shelby in a few years to replace the challenger, or I may splurge and get a hellcat instead.
