Hey Bhave07,
The FT Rankings have been around for the longest as compared to the others. They also follow a comprehensive ranking methodology, taking 17 factors into account ranging from Salary Increase, to the Number of Female Students, to International Mobility.
QS Rankings are also very reliable, and have been followed for a long time. They follow a robust methodology focused mainly on Employability (35%), Value for Money (20%), and Thought Leadership (20%).
The Economist Rankings follow a more dubious process during their Rankings. They regularly update their process, which is why the rankings deviate often from year to year. Economist puts a lot of emphasis on Student Diversity and Faculty, and less on Increase in Salary. Hence in my opinion, it would be better to follow other rankings.
You can also follow the local country rankings and subject-wise rankings, both reliable sources of information.
Bear in mind though, choosing schools based on rankings alone is not the right approach
Instead, choosing the best school requires close introspection of the following things:
1) Where do you see yourself working post-graduation
2) Which field do you want to work in
3) If you want to learn a new language or not
4) Which country do you prefer to study in
5) Are you aware of the immigration policies of your target country
Think about these points, this will help you narrow down your school list to 4-5 target schools, which you can then apply to.
