No, AIIMS Delhi is India's no. 1 college and not the world's no.1 college. Rank-wise, the top colleges in India are

• AIIMS Delhi
• CMC Vellore
• BHU
• KMC Manipal 
• JIPMER 
• KGMU

If you are looking for top medical colleges across the globe, here are a few.

1. Harvard University, USA- Situated in Boston, it has been ranked the best medical college by Times Higher Education World Ranking; QS Best College ranking, and by several other rankings with an acceptance rate of 4 % only. 
2. University of Cambridge, UK-. The medical school provides top-notch research opportunities in addition to superior-quality medical education.
3. University of Oxford, UK- It is the oldest University in England. A plethora of courses are offered from which you can choose the ones that intrigue you. Some such subjects taught are diagnostic imaging, neuroscience, clinical embryology, and others.
4. Massachusetts Institute of Technology (MIT), USA- MIT’s Medical School is in collaboration with the medical school of Harvard University. But it’s important to note that it is a completely different school from Harvard’s Medical School.
5. Johns Hopkins University, USA- This old university is known for its excellent research and education in medicine and public health. This university is an excellent option for medical aspirants. 
6. Stanford University, USA- This is a well-regarded research-driven medical school that provides excellent education and research opportunities to its students. 

So, India's No. 1 medical college is AIIMS and internationally it is Harvard University followed by many others.

No, I don’t think BITS Pilani is overrated in any way. In fact, it deserves the hype it gets because of its standard of education and the opportunities it offers. 

BITS is certainly comparable to IITs in terms of academics and faculty. It only seems a bit lacking in terms of research although it has been improving gradually.

BITS tag makes it easier to secure a Master’s in foreign universities. The average GRE score for a BITSian is around 330/340. Thus portrays the excellent English-speaking culture of BITS.

Being a part of the BITS family gives you access to its elaborate alumni network. Its alumni are working successfully across the globe and can be found everywhere be it the UK, US, Germany, France, or Singapore.

BITS Pilani Practice School is a compulsory graduation requirement for all students that comprises Practice School I and Practice School II. Practice School I is an internship of 2 months for students at the end of their 2nd year and Practice School II is an internship of an entire semester, around 5 -5.5 months either in the odd semester or the even semester in the final year. 

We can safely conclude that BITS Pilani is nowhere overrated and it certainly deserves all the hype. 

Comparing School of Engineering CUSAT and Jamia Millia Islamia is not suitable as both the colleges are well established and are holding their culture and curriculum really very well. So, choosing either of them would not be easy.

But, as far as I know, Jamia Millia Islamia was established 100 years ago and is better than SOE CUSAT.

Jamia Millia Islamia will offer you a productive and competitive environment. You will also get to do lots of extracurricular activities and will get to learn from highly efficient teaching staff in JMI.

In CUSAT, you might be taught by recently graduated teachers. This will not only affect the teaching methodology but a good exposure as well.

CUSAT is nicely harnessed and handled by various Political parties for their own benefit. You can see a few strikes now and then among students and parties. But it should not be your concern as you are going to study there and grow productively.
