Mississippi is generally known to have more in the way of culture (the Delta blues started there after all) while Bama obviously has a lot more sports history. A lot of the deep south is very similar although I know people have different definitions of what makes it up. On the fringes it definitely bleeds into some states that aren't all the way deep south (like Florida). I might argue appalachia in general is shittier than the deep south. Or the great expanses of nothingness in the north - Idaho, Montana, the Dakotas etc.
I am I - you are you. These are irrefutable truths. Possibly.
