Both are good universities but speaking from my personal experience I would like to say that  Lovely professional university is a good university because my younger sister is studying in LPU , It is very good university .

LPU is Ranked 14th Best Private Engineering University in North Zone.so it is a university which is one of the best engineering university. I have also misconceptions about university but when my sister took admission in LPU than I got to know that it is one of the best private university

Under given are some points ,one should look for before choosing a campus

Infrastructure

Accreditation

Placement

International experiences

Ranking

Campus Life

Facilities

Teaching quality

Safety and security

So according to me ,you should choose LPU

Both the colleges are good but if you want to choose any one between the two you can go for Jaypee Noida it has better ratings than LPU.
