The Madras Institute of Technology (MIT) is one of the four campuses of the larger state university, Anna University, of the state of Tamil Nadu. The placement process for all these four colleges happens simultaneously in a combined process. 

The placement data for MIT Chennai is given below along with the data of the Hindustan Institute of Technology and Science (HITS or Hindustan University) for the year 2018-19.

So undoubtedly, MIT is better than Hindustan University in all respects as well as placements. Anna University placements are even sometimes comparable to some leading NITs and IITs in some branches such as Computer Science and Engineering (CSE). So, you can obviously realize which is better for you in terms of placements.
