MRCET  is better than MREC infrastructurally as well as placement wise.

• MRCET has better infrastructure with separate blocks for every year students.
• Most of the faculties in MRCET are dedicated to lectures and are also involved in research. Thus the convenience of student is taken care of.
• MRCET has sports and cultural conduct facilities for the interested students so that the passionate one can pursue it apart the course.
• MRCET conducts placements in which more number of companies visit than the MREC. Thus the probability of getting a job via placements becomes higher. Non-CSE background students also get desirable jobs.

I hope my answer helps you. I will also recommend you to have a research about both of this college and then decide where to take admission.

Have a great day. All the best for your future endeavors!
