That will be tough to answer due to all the different dialects and accents that both languages have.  For instance, in the US someone may love the "southern drawl" but hate the "Boston brogue".  On the British side, how does one compare a Cockney accent with a Scottish accent?

There are so many different dialects in America: there's North-Eastern(New York, Pennsylvania, etc.), the South Eastern(Georgia, North Carolina, etc.), South (Texas, Oklahoma etc.), Central(Idaho, Michigan, etc.), West coast (California, Washington, etc). And that doesn't even count the "city accents" like Philidelphia, Staten Island. Long Island also has it's own accent. I live in New York and there's at least 3 different accents just around people that I live close to (Pennsylvania, New Jersey, Long Island) I don't think it's fair to compare! If you're talking about different dialects, it'd say there's mostly just three, South, Hawaiian, and everywhere else.

I guess is British language , because it is more correct.

English sounds beautiful? Hahaha I am not trying to badmouth my native tongue (New England American English) or British English either but I think most Americans would say th

e Romance languages like Spanish, French, and Italian sound prettier and are the languages of love. Sorry for not listing Portuguese or Romanian. I know they are Romance languages too but I don't think people really get exposed enough to them to know what they sound like.

Every accents are beautiful :)
