Comparison Amelia Walter-Dzikowska draws from an earlier discussion panel. Working with native English speakers exposes you to authentic accents and sophisticated vocabulary/grammar but also to heavy regional slang, proverbs and cultural layers foreigners won't always know. Working in an all-international-English team among fluent non-natives tends to produce simpler, clearer, more concise speech and reduces the emotional and cultural layer — everyone is equally 'disadvantaged'. There is no single correct team composition; both options have pros and cons.
