British Or American English?

What is the difference? Which one is better professionally in India? Which one should I learn?
Sharing a brief exploration into whether British or American English is better for you.

It's more of a false dichotomy created by training industry. Language is one, though there are regional differences in usage, pronunciation and spellings.
The same way as the flavor of any other language changes with location.
You need to be aware of the differences but its not as if there are two types of English!
