Which is better after graduate in civil: an M.Tech in transportation engineering from an IIT, or construction management from an IIT or NICMAR?

IIT Delhi and IIT Madras offer a Post-Graduation in Construction Technology and Management. To secure a seat at either of the institutes, you must obtain a good rank in the GATE examination.

IIT Delhi gives more weightage to the technical aspects of the course, while NICMAR focuses more on the managerial aspects of Construction. The curriculum of the course is unmatched, yet the placements, at times, can be quite unanticipated. 

Both the courses are quite equivalent to each other on various stages whatsoever. But, when the decision boils down to which among the both is better, then IIT Delhi might win the race.

Now, the Transportation Engineering department from IITs is indeed a great course. The average package some of my seniors from this course secured was about INR 5 LPA. However, by all means, your placement partially also depends upon whether or not you are typically prepared for it.
