I am neither English nor American, but as a foreigner, I think that UK oral is the best choice, because in American oral, there are more overlaps of words, which affects the euphony and the articulation of words.

Guys care little about accent. We care how you look.

I guess it is all about accent. The one you like most yourself is the one you should choose. As for me I'd say that Queen's English accent is the one I like most. For girls, especially ;-) But, anyway, as Paul had said, there is not much difference which one to choose.

They are very much the same so it would depend on how you are going to use the language, were you plan on working or travelling to. But to be honest I don't see much benefit of one over the other in terms of speech. They only really differ in terms of spelling, such as colour (uk) and color (usa)
