Hello aspirant, I'll suggest you to go for chatrapati sahuji Maharaj university. Placements : Chhatrapati Shahu Ji Maharaj University, Kanpur is one of the prestigious universities of India and engaged in the process of providing quality education along with great placement records. It has a great reputation in the state and surely you should choose this. 

Institute of Engineering and Rural Technology , Prayagraj (Allahabad) IERT is a developing high quality institute of international standards in order to meet the needs of the fast generation but this college is still in the developing state. So according to me you should go for the previous. 

All the best. Feel free to ask more questions.
