IT at IIIT Una is better than CS at KNIT Sultanpur. The reasons for the same are given below.

• Infrastructure - IIIT Una does not have its own campus yet. Currently, it is functioning from NIT Hamirpur campus. Thus IIIT Una students enjoy the same great facilities and the lush green campus as NIT Hamirpur students. KNIT Sultanpur has average to bad infrastructure.
• Locality - Again the temporary campus at NIT Hamirpur is much better than Sultanpur.
• Education - In this regard, both may be equal but owing to better facilities being provided by NIT Hamirpur, IIIT Una will be considered better. The fee is almost the same in both the colleges.

It is advisable to talk to some of the current as well as recent alumni of both the institutes to know the exact state of the colleges and their placement records. IIIT Una is still very new and evolving. KNIT is also a good option but looking at other things and the future growth potential IIIT Una should be preferred.
