Those are all claims about the accent (my understanding of said claims is basically "sounds reasonable but also I have no idea what I'm talking about").

I was more thinking about the words/grammar/idiom etc.

(also as a Lancastrian I find e.g. Deep Somerset barely comprehensible, especially when the speaker is a few pints in, but their wording is still usually closer to mine than the USians' is)
