In Expressions^x, British accent^x, American English^x

All I know is that British accent sounds better but surprisingly...however, I'd rather to speak the American one because words come out easier regarding the pronounciation..of course sometimes when I watch some American movies is unavoidable to dislike some colloquial expressions...some used...

Yes. I live in California, U.S. of A. I am a native speaker of American English. I'm also familiar with British English but I do not speak with a British accent! The accent and some of the vocabulary and expressions (especially slang) are about the only things different between the two.
