American is #1 in accents, just like about everything else
“There are quite a few British accents- an amazing amount actually, particularly considering the entire UK could fit into Texas, and England itself is only about the size of Alabama. ”
Not quite amazing, if you consider that there are literally dozens of distinct ‘accents’, even within a state, and many states have their own distinct accent. The “Southern” accent you are probably referencing is quite different and distinct in Georgia than in South Carolina and different again in Virginia.
