Hey!

Comparing in terms of infrastructure and other facilities:

VIT> Thapar > LNMIIT > JIIT

Comparing in terms of placements:

Thapar/VIT > LNMIT > JIIT

VIT vellore and thapar institute are popular for its placement records and are considered as the top engineering colleges in India. Also, when it comes for fee structure Thapar and VIt charge a low fee compared to LNMIIT. however JIIT also offers good placement opportunities to students but are not as much good as VIT or Thapar.

Hope I answered your query.

Thankyou
