A few of my friends graduated from VIT Chennai and KIIT and here are some insight from their experience which may be of help.

KIIT will be a better choice just because it's the main campus, the placements are almost at par and you get more freedom to enjoy college life.

But VIT does have an edge over many things, and even if you go to VIT Chennai, the placement opportunities will be the same.

Here are the recent placement statistics for the institutes.

Consider other factors as well, things like which is nearer to your home town, where are your friends going, the fee structure, the branch you are taking, etc

ECE and CSE are two different departments, providing separate career opportunities. VIT Chennai and Amrita University Bangalore offer decent placement to students in these departments.

The points below give a brief overview of both the choices:

• In CSE, there are excellent package offers in institutes like Amrita and VIT, thus increasing your chance of getting a good salary at the beginning of your career.
• ECE is a stream of a kind, which has its own charm. In ECE, students grow slowly with time and earn decent salaries, provided they are passionate about the field of work.
• ECE in VIT Chennai is a great department, having a world-class infrastructure. The curriculum is at par with the industry needs. The professors at VIT Chennai are connected to the industry and other academic institutes to aid in research.
• All major electronics companies visit the campus of VIT Chennai for placement. Almost 20% of the students in the department get a package above 10 LPA in general from companies like Samsung, TI, Nutanix, etc.
• A major percentage of about 70-80% of students in ECE at VIT Chennai get a package between 5-8 LPA. Companies like Cisco, Intel, Wipro VLSI, Arista Networks offer salaries in this range. There are also some non-tech companies like Deloitte, E&Y, Bank of America, PWC, Wells Fargo, etc that recruit students from ECE.
• In VIT Chennai, there are very few students who opt for job offers in service-based companies like TCS, Accenture, Infosys, CTS, etc.

Therefore, both ECE at VIT Chennai and CSE at Amrita Bangalore are good options. It is the choice of the student as to what excites him/her the most and opts for a degree in the same.

Both of these colleges are good. VIT is the best private engineering college in India. Whereas CUSAT is also a reputed institute. CUSAT is a government college, and VIT is a private college. Thereby, you will get a better facility in VIT rather than in CUSAT.

Hostel Facilities: (Winning Institution - VIT)

However, the hostel facilities are also not up to the mark in CUSAT. But VIT offers good hostel accommodation. But VIT charges a lot for hostels. 

Course Fee & Infrastructure: (Winning Institution - VIT)

• The education fees for entire engineering courses in VIT are around 16-18 lakhs, including food, lodging, and education fees. In comparison CUSAT charges around 8 lakhs for the same. Thus, VIT is quite costly. 
• But it can be mentioned that VIT is far better than CUSAT. The better infrastructural facilities in VIT assist the student in their entire courses. Whereas in CUSAT, college infrastructure is not like VIT.

Placement: (VIT ~ CUSAT)

You will get good exposure in both of these institutes. Placement records of both of these colleges are also outstanding. If you work hard, you can bad a decent salary package from the campus placement from any of these colleges. 

The table below gives a brief overview of both institutes. 

If you want to get better infrastructural facilities and good food and lodging, then you should go for VIT. But CUSAT is more affordable and it is also a good choice with excellent placement statistics.
