IIT Indore is a good choice among the three options for computer science and engineering (CSE). The reasons for the same are as follows.

• It has a good coding culture and has grown tremendously in this regard. The students proved this in the international ACM ICPC contest.
• Indore is not only a good city, but it is also a local IT hub with a reasonable number of good companies in the vicinity as compared to Dhanbad or Mandi.
• The placements are more or less equal for the three institutes. So, it cannot be the deciding factor.
• The overall growth of the institute is also very impressive.

So on a preference, IIT Indore will come first followed by IIT Mandi and ISM Dhanbad.
