If you want to settle abroad, then obviously university abroad is best depending on the place you want to settle in and the best university there, but if you want to settle in India all of them are best based on certain criterias Like:
1) Your Percentage
2) Which Institute exactly?
3) simply doing it from any university abroad will not giving you any weightage in our country too.
4) And irrespective of you holding any degree from IIM, IIT and not proving yourself excellent and a wonderful asset to the company will of be no use either. So Work Smart and hard but don't slog and remember even people from government schools and colleges are idols for people and proved themselves good, so, your smart and good work is more important than the names of the institutes.
Wish you luck.
