Good Afternoon

As per your query it's little difficult to say which one is best but from some factor we can decide which one is better

Establishment : Jaipur National University is established 2007 on the other hand Poornima University is established on 2012, both are private Universities.

Fees and Salary: Fees of Jaipur National University is 1.44 lakhs for 3 years of B.Com and highest salary is 27 LPA and Fees of Poornima University is 1.40 lakhs for 3 years of B.Com and highest salary is 25.33 LPA

Accreditation and Approval: Jaipur National University is UGC approved and has NAAC B accreditation on the other hand Poornima university is UGC Approved and Jaipur National University has more facilities than Poornima University

So, now according to me Jaipur National University is better option than Poornima University
