I still find it weird to generalise accents by nationality, seeing as how there are so many accents in each country.
You can't possibly say that people from New York sound like Texans, or Londoners sound like West Countrymen.
Personally, I quite like the Yorkshire accent, on some people.
Other than that, I quite like my Oxfordian accent.
So, in general then, to fit with the poll, I choose "English".
Least favourites are probably Scouse, Glaswegian and then certain Irish accents which I couldn't place by location.
