Which English you like?

I prefer both but in formal situations i use british english and informally i use american.

I am a Chinese university student majoring in English. The fact is that most of the Chinese just mix up the two and it is hard to recognize whether they speak British one or American one. British English is the standard, but I like the pronunciation of American English more. Maybe there is the matter of economy nowadays. There are more chance for us to touch the American English. American English seems more simple and casual, thus many young people prefer it to British one. Seems like a kind of fasion. Few students in my iniversity insist in one of them. It is just hard to divide them. I have to admit that I am also a mixer. I just have no that kind of insistance in one of the two.
