I think they're all nice, British accent if I had to name one, probably. What about you, Andrew? :)

For me, it depends on the situation. I like hearing the Australian accent because I'm Australian, and it makes me feel at home. Some British accents are nice to listen to in general. I think the Scottish and African American accents sound really cool. I think a North American accent sounds the best for singing in English.

undoubtedly american accent. American accent is so cool and easy going whereas british accent is tough to understand. It's absolutely my opinion.

You'll probably find the Aussie accent difficult. I grew up with non-native English speakers in my family, so I became good at keeping my vocabulary and accent balanced so people can understand me. But I can also lay on a thick Aussie accent when I want to, lol

I like American accent
