Hello Droid 

Both these colleges has mixed reviews but according to the survey or i can say the feedback which i got from my friends studying in these colleges, i will go with LMNIT.

Campus - LMNIT (obviously)

Placements - Both are somewhat simillar but no. of applicants are higher in JIIT

Feee- Again same

LNMIIT is not totally a private institute, it is run through a public-private partnership model. LNMIIT was set up in collaboration with the Government of Rajasthan.
