What is the true ranking of NITs and IIITs for CSE in all respects?

My friend got a rank of 13471 in JEE-Main 2019 and after a lot of website research and references from other people; he has come up with the top 10 rankings for 2021:

1. IIIT Hyderabad: It has the best faculty for CSE with very hectic college life and rigorous curriculum. Placements are very good here and can be easily compared to those at the top 6 IITs, BITS Pilani, and a tad better than NIT Trichy. 
2. NIT Trichy: Undoubtedly the best NIT which is a class apart from the rest. The administration is not up to the mark, but you’ll learn to manage on your own. Also, it is supposedly better than most IITs bearing the top 9.
3. NIT Surathkal: You will get really good placements and the exciting part is that the college has a personal beach so you can enjoy it to some extent.
4. NIT Warangal: The placements are quite at par with NIT Surathkal but except for the beaches.
5. NIT Allahabad: You won’t get a happening college life or good infrastructure there but the placements are quite good. The Alumni base of the institute is also decent.
6. IIIT Allahabad: The placements are a bit better than NIT Allahabad, but are ranked lower due to its reputation and college life.
7. IIIT Delhi: You can get a good potential for research especially if you belong to the A.I domain. The branches offered are also quite unique (some similarity to those offered at IIT J, IIT H, or BITS) which will really help you to apply abroad for research.
8. NIT Jaipur: The placements are okay and it is one of the top NITs. Although if you go get in the CS branch then you’ll surely get somewhat better placements than your counterparts.
9. IIIT Bangalore: The placements are very good here but it is ranked so low because it only offers 5-year programs. The fee is also much greater in comparison to the NITs.
10. NIT Rourkela: One of the oldest colleges and finds its reputation due to the NIT tag. The alumni base and the placements are all good here.

Apart from the top 10, here are is the ranking for the remaining ones:

NIT Kurukshetra> IIIT Gwalior> NIT Hamirpur> NIT Surat> NIT Jalandhar

To sum up, every college comes with its own pros and cons. Thus, setting up your preferences might help you get a clearer opinion whether you want excellent placement, campus facilities, college life or a little bit of all.
