I don't think there's neither an english called "The best english" nor a spanish called "The best spanish" because there's just one english and this is divided into some "Dialects (UK and american)" and you can choose study either uk english because of its sound or american english because it's a more global english dialect, personally I'm studying the UK dialect because I like it's sound :D I come from Chile and the chilean spanish dialect isn't worse than spanish dialect, they're only different dialects and sounds. just that :D

Which English is the best?

Hi guys!
I am learning English, and sometimes I ask myself, which English is the best?
British, or American? For example in Spanish, the best place to learn is the country of Spain, because it has the best pronunciation and most correct dialect.
Overcoat, the Spain interior. (No entiendo este oracion..)
I await your answers and opinions
Thanks!
