Well according to me the list should be something like this,

1. NIT Trichy
2. NIT Surathkal
3. NIT Warangal
4. MNNIT Allahabad
5. MNIT Jaipur /NIT Calicut
6. SVNIT Surat / NIT Nagpur
7. MANIT Bhopal / NIT Kurukshetra / NIT Rourkela
8. NIT Durgapur / NIT Jamshedpur
9. NIT Jalandhar ( Estd. 1987) / NIT Delhi ( Estd. 2010)
10. NIT Raipur/ NIT Hamirpur (Estd 1986)

These are the NITs which were RECs / RITs (Regional Engg College/ Regional Institute of Technology) before. and were established in early 1960s (unless otherwise mentioned). They have better alumni base and infrastructure as compared to newer ones.
