I'll tell this story with 3 pictures. I don't like the widebody on the Challenger. It seems like an afterthought implementation. The Charger's widebody looks nice... but I have never driven a vehicle with 4 doors, and I don't plan to anytime soon... so no Charger for me. But, look at what I mean:
First, here's my narrow body. It has classic, clean lines:

Compare to the WB Challenger:

Then, the widebody Charger:

Now, the Challenger's fender flares look like they are literally 3M taped onto the side of a NB Challenger. It looks like they were slapped on, and then the design team went home for day and called it quits. Then, you have the stupid side marker lights that wrap into the flares (this is a critical engineering shortcut fail of BLEH proportions to me). Now, compare this to the Charger. The fender flares flow into the rocker panels and that wide stance is carried almost all the way around the car. The marker lights are angled to fit within the flares. It is a MUCH more clean design. With the Challenger, I look at it like it's just horrible. Where, if I had to own a Charger, I would have to have one with the widebody because it looks really good.
So, that's why I went NB Challenger. The performance benefit of the widebody in actual street use is negligible, unless you're doing twisty track work. And, if you're doing that in a Challenger, I hope it's for fun and not competition. Even a WB Challenger is still a dog on a race track. It's just the difference between a St. Bernard and a Great Dane. Not exactly an agility dog
