Perhaps you were just exposed to more American TV? Watch some BBC dramas to balance it out.

Hi I am Ronald from Ecuador. Well, as you know, the difference between British and American is; American english pronunciation it's more clearly, easy to understand but as you know american english is derived of British. And both have hard level. In my opinion American English it's more easy, but both are ok, all depends of you.

British English is simpler and easier to learn. The rules are clearer. There are fewer acceptable variations.

I could say British english is alil bit complicated due to some restrictions namely ,Grammar,Sentence constructon and so on,But an american english is considered as smooth one
