In response to that question (© Peguy), I was wondering who you consider to have the "more" annoying English accent.
And if you want to elaborate a little bit further, we could separate this question into two sub categories:
1/ Most annoying accent for native English speakers
2/ Most annoying accent for non-native English speakers
Of course, if you feel more optimistic than pessimistic (© Lark), you can feel free to tell which accent you prefer too!
