As a reflection of the sheep mentality, the majority of engineering aspirants can be seen running after CS or IT. However, I will suggest you also give preference to your interests first.

Electronics and Computer Science Engineering is a recently launched branch at KIIT and is actually great. Not many batches have passed out yet, but the branch seems promising like any other branch at KIIT.

• In the first year, the same foundation courses are taught that are common in all the branches. These include Physics, Chemistry, Basic Electronics, Engineering Mechanics, etc. 
• From the second year, you will be intrigued by the ECE concepts. Out of the overall curriculum, approximately 55% weightage is given to electronics subjects and 45% weightage is given to CS subjects. 
• From what I have heard, the subjects taught to ECE are easier than the subjects taught to CS and Electronics students individually. 

In all, Electronics and Computer Science Engineering is a decent choice especially if you are interested in the field. However, if you are still aiming for CS, then you can opt for a branch change after one year. The cut-off for branch change is 8.5 CGPA but to get into CS you will need around 9.2+ and 8.9 or more for IT.
