IT in SGSITS is better than CSE in IET DAVV. It is older and more recognized in the industry. It has an excellent student crowd. The environment on campus is competitive. 

SGSITS placements are great for IT, due to the legacy of the institute. The median CTC of the branch is INR 5 LPA. L&T Infotech, ZS Associates India Pvt. Ltd., and Adani Group are some of the major recruiters for the branch.

I would like to highlight a few points in favor of choosing IT at NIT Surathkal-

1. IT and CSE have more or less the same curriculum.
2. NITK offers excellent placements. This is especially true for circuital branches- CSE, IT, ECE and EEE. Top students from these branches are offered placements at brands like Google and Microsoft.
3. NITK is a brand in itself. Since it is an NIT, it offers much more exposure and opportunities. 
4. NITK admits JEE Mains toppers from all across the country. So it has a very rich crowd.
5. As a Bangalorean, you can frequently visit home from NITK. 
6. As a hosteller at NITK, you’ll learn important life skills. 

Thus, based on these factors, I would recommend you choose IT at NIT Surathkal over CS at RVCE Bangalore.

The quality of Education, the faculty pool, and even the lab facilities offered at both IITs are similar. There might be slight differences as far as internships are concerned because the top companies with coding profiles visit both IITs but the interview process is quite different. 

The main reason for this difference is the location of both institutes. In the case of IIT Kharagpur, recruiters prefer taking a skype interview than personally visiting the campus because of the isolated location of the institute. This plays against the favor of IIT Kharagpur as face-to-face interviews are way better than online interviews. Online interviews do not convey the information and expressions rightly and there is a communication gap.

Companies tend to judge IITs based on rankings which depend on their respective placements. For instance, the same profile and role are offered with a higher package at IIT Kharagpur but with a lower package at other IITs.

While IIT KGP CSE has a wide scope if you have achieved a top JEE Rank and have managed to get into IIT Bombay, go for it.

You should choose Acharya Institute of Technology ISE. It is the best engineering college in Bangalore. It offers good academics and extra-curricular. The ISE department has a brilliant faculty base. For ISE, Acharya Institute of Technology placements are pretty good. Students receive an average CTC of around INR 11 LPA - 12 LPA. Many core companies visit the campus placements. ISE students usually get recruited as coders, analysts, testers, data scientists, etc.

SRM Easwari Engineering College is better for CSE. The placements are great. Around 80-90% of students get placed from the branch each year. The average CTC received by the students is around INR 4.04 LPA. Students of CSE get recruited in software development,  data science, and other core areas. Zoho, TCS, Amazon, etc. are among the major recruiters to take part in the placement drive.  

My JEE Mains rank was good enough to get me a seat at SVNIT for B.Tech CSE. I finally decided to join ICT at DAIICT because-

1. The faculty members have completed their Phds from renowned Indian and foreign universities, and each of them are actively engaged in some research work.
2. The course curriculum is regularly updated, unlike the NITs that keep on teaching the old curriculum for long periods of time without regular updates.
3. ICT is a combination of CSE and ECE. So its curriculum is very broad and rich. This is the reason why more companies prefer DAIICT over SVNIT.
4. Only about 360 students are selected for the B.Tech program of DAIICT every year. This speaks volumes about the quality of students on campus. 
5. A good number of DAIICT students are selected for GSoC.
6. The coding culture is at par with IIIT Hyderabad and top IITs. DAIICT students go on to become ACM ICPC finalists. The environment is perfect for competitive coding, and the students are doing really well on popular competitive coding platforms like Hackerrank.
7. The clubs and societies of DAIICT are very active. There is an IEEE Student branch, with IAS (Industry Applications Society) chapter.
8. There are special interest groups for machine learning, mobile apps, artificial intelligence, etc. There are technical clubs like Programming club, Google Developers Group, Microsoft Students Technical Club, Webkit, etc.
9. Some of the non technical clubs are- the Debate club, the Press club, the Dance club, the Music club, and more.
10. The SBG-Student Body Government is a mediator between the administration and the student community. The seniors of SBG are very friendly and helpful. They can be approached with any problem.
11.  Like SVNIT, the DAIICT campus is also ragging free and very safe for juniors. 

I would recommend you opt for ICT at DAIICT Gandhinagar.

First, I would like you to address your branch preference. Choosing a branch should be the top most priority. CSE and ECE are quite different from one another. Although IITs/IIITs/NITs do offer a branch change option, it is quite difficult to get it. So I would suggest you make up your mind on which branch truly interests you.

Now coming to the colleges. Choose IIIT Jabalpur for a CSE branch. This is because IIITs offer good placements, curriculum and culture in this branch. Even IIIT Kancheepuram is a good option for CSE. But the distance from home and food form an integral part of this decision-making. Assuming you aren’t from South India, the lifestyle and eating habits might be difficult to adapt to. As far as NIT Hamirpur and NIT Jalandhar are concerned, choose them if you are planning for an ECE degree. They are good colleges as well. 

First prioritize your branch and then choose your college among these four. I won’t suggest you go by college rankings. Basically, choose your branch first and then decide the best college for yourself.
