None of the IITs now compete with international institutions. IIT Kharagpur is a great option only if your future plans include moving to India. IITs are not as valuable as premier institutions in the US, UK, France, and Switzerland globally. There are various reasons for Harvard to stay in the upper hand that Indian institutions, they are as follows:
So, in conclusion, selecting Harvard over IIT Kharagpur offers global recognition, a diverse learning environment, and access to a broad range of fields. However, financial costs and cultural adjustments are important factors to consider. Ultimately, the decision hinges on individual goals and priorities, weighing Harvard's prestige against personal circumstances.
Honestly speaking, none of the IITs are at the level of foreign universities today. IIT is an excellent choice only if your prospects involve settling in India. Globally, IITs lack the necessary worth when compared to top US, UK, French, and Swiss universities.
In case you want to settle abroad then the kind of universities that will help you do so are MIT, Harvard, Yale, Oxford, Cambridge, and the Sorbonne only. Sadly, IIT is still not credible enough to help you settle abroad.
There are other reasons as well why IITs are considered inferior to top foreign universities like Oxford. At Oxford, you will find such a diverse peer group of geniuses that the learning experience will become excellent. There are many who study unique subjects like History, Latin, Greek, Modern Languages, English, Engineering, etc. When you end up befriending such geniuses, it adds to the overall experience. You basically get to spend a lot of time with intelligent people with unique interests and this helps you develop holistically.
This diversity is definitely lacking on the part of IITs and they have a long way to go.
