As you will no doubt know, there are many differences between UK dialect and US dialect (pronunciations, for example). However, which do you prefer out of the two?
Personally, I prefer UK dialect, because I personally find it easier to understand, and I'm also used to the pronunciations. I don't really like the US pronunciations of some words (I'd rather have tom-ar-to than tom-ay-to), and I can't really understand a Southern US accent very well, though I can understand a generic US accent relatively well. I guess I am a bit bias though, considering I'm British myself.
