It's possible that IIIT Delhi is superior to IIIT Allahabad because of its prime location and excellent faculty and placement statistics.

• IIIT Allahabad is also a National Institute of Importance, but IIIT Delhi is not.
• The coding culture isn't even close to being equivalent; IIIT-D is far superior.
• Professors at IIIT-D are generally PhDs from prominent universities throughout the world, therefore their experience and letters of recommendation are quite valuable.
• Another plus for Delhi is that the research climate is excellent, especially for undergraduates.
• Technically, neither has “100%” placements, but their placements are extremely similar overall—Delhi to Allahabad.
• The differential in tuition prices is the most compelling reason to pick IIIT Allahabad over IIIT Delhi.

For the time being, the positions are identical, although Delhi is considerably younger and already has similar placements. It also appears that the overall atmosphere in Delhi has improved.
