I'm not a fanatic of accents. Any accents of English are fine to me if I can understand the speakers' well. I think I just can distinguish the accents bwtween Americans and Britons, and I am not familiar with other accents.
Personally, I prefer the accent of the Queen's English, but many Chinese love American accent more.
It is very hard for many of us Chinese to understand Indian accent of English. I was also discouraged by a kind of Australian accent. My supervisor who is a Chinese understood him well but I failed during our meeting. The only word I caught from his speech was container, which that Australian pronounced as 'con [kon]-ta[ta:]-ner. But I understand speaking of other Australians' well.
