People who've lived in India and a foreign country (atleast 2 years), what difference did you find?

In all aspects, quality of life, lifestyle, income, availability of stuff, happiness, security, corruption, all the pros and cons which you can compare. Please mention the country, your age(a rough estimate should help), domain in which you work/study (basically how did you move), and would you settle there? Return to India or somewhere else? Thanks
