As per the WEEK 2019 ranking ITS Ghaziabad is at 39 position and IMS Noida at 60. The infrastructure of both the colleges is almost equal.
However, when it comes to placements, ITS has an upper hand. There are good placement opportunities in ITS as compared to IMS. Since placements are very important consideration in MBA, I would sugges you to consider ITS.
Hope this helps. Thank you.
