The old saying "Chrome won't get you home" as been around a long time, although I do feel it is often taken out of context.
The original meaning was that chrome accessories, bling, etc, does little for you on the trail, and spending the money on axle shafts, armor, winches, etc, was a better use of the money.
In simple terms functionality beats appearance. Which is hard to argue with as far as the trail goes, and the same applies to CJ's and other Wrangler models.
I'm not a chrome fan on vehicles personally, as it requires more maintenance than something that is painted black, especially if you wheel your rig. That said if someone wants to have a good looking rig, I don't see anything wrong with it.
There is also a difference in types of bling. Again just my view, but I think the stick on chrome stuff looks cheap and tacky, but some chromed billet door handles would be nice bits of bling furniture that may accent the look of a vehicle.
In reality there is little difference between chrome and someone going for the "murdered" look of everything blacked out, smoked lenses, etc, they are both done for appearance.
Choose your own poison and enjoy it, don't worry about what others say.
