I will not do any comparison between these universities as I know only about Lovely Professional University but do not have any idea about Amity and Chittkara University.
Being alumni of LPU, I always recommend my friends and relative to do an MBA programme at LPU only. I will tell you why LPU.
The Business School of LPU is accredited by ACBSP, Accreditation Council for Business Schools and Programs from the USA ensuring quality education and industry-experienced faculty members, studying in LPU will get a degree accredited from a body of USA. LPU is ranked No. 2 among Indian B-Schools in ‘Outreach and Inclusivity by NIRF ranking released by MHRD, Government of India.
