But, however, Thapar University is a better option for mechanical engineering when compared to PEC.

In terms of cut-offs, DCRUST seems more competitive than Thapar University. However, placements is what matters.
Thapar University will expose you to some great companies like Amazon, D Shaw, Sandisk, ZS and Deloitte which might not be same with DCRUST. If your pocket is not constrained you should go for Thapar else DCRUST is a good choice considering a comparison between the same engineering branches.

Considering your question to be regarding B.E. courses,
In my experience ECE is a much recognized and preferred branch over EIE due to its established market demand and better recognition and a well tested curriculum. In terms of cut-offs for admissions for B.E. EIE lags behind B.E. ECE in Thapar and so in the placements.

Let me correct you its BE mechanical engineering not B.Tech in Thapar University.
The BE mechanical engineering programme is accredited by the engineering accreditation commission of ABET. The department has aligned its curriculum with that of Trinity College Dublin (University of Dublin, Ireland) as part of the academic collaboration to impart global standard education to the students.
Only handful of colleges throughout India hold this Accreditation.
If you go back to history, B.E Mechanical Engineering in TU was considered the best in terms of facilities, faculty, and placements and this continues till today.
Opportunities that you will get after completing BE in Mechanical Engineering will include tech as well as non-tech companies with packages varying from 4-8 LPA and 4-12 respectively.
