Dumb question - difference between Dodge and Plymouth

In sales, from at least the sixties,Dodge sales always seemed to be better than Plymouth, even tho Plymouth pricing was usually lower. I think it was a public perception that may have harped back to the war,and possibly/ more probably to advertising.
Dodges were usually; bigger,heavier, longer,better-optioned and often more powerful.

IMHO, Plyms were always better looking, lighter, and usually;faster and quicker.WAaaay better looking.lol.
