Hi,

In my opinion you should go for KIIT's CSE.

Both the colleges are the most important colleges after IITs, NITs and some reputed government college and private colleges such as BITS and VIT, Vellore.
Both the universities are deemed. In 2017, SRM University ranked 35th position while KIIT University ranked 47th. But faculty in KIIT is quite better than SRM University. The diversity in SRM is more as it has 7 campuses.
In Chennai campus SRM provides good placements but in all other campuses placement record is average and in KIIT if a student scores more than 6.5 CGPA in B.Tech then he/she definitely gets a placement. So placement condition in KIIT is good.

KIIT is one of the underrated colleges in India, despite its excellent achievements, academics, placements, it fails to show up to the top college's roundup. Clearly, it is not a pump and show at all.
It is much more concerned on your academics than SRM is. At SRM, you have to learn everything by yourself, get out of the place where you expect the teacher to guide (other than a few), but the staff is really supportive and guiding at KIIT. The fees on an average as per 2017 is lesser for KIIT and you don't have to pay loads for a hostel at SRM. Much better and bigger placement take place at KIIT. So now, to sum up, it is clear from there records that in the coming future it will prove to be a better institution keeping inside the brand name of SRM. Also, course regulation supervision and revision takes place every year at KIIT which is something SRM lacks and keeps using the same old 5 year back course.
KIIT only if home education and placement are what you want.

In overall comparison KIIT is a good university which has transparent system of education but in SRM University condition isn’t the same.
Fee structure in KIIT is fixed i.e. 1,50,000 INR but in SRM it depends on many things.

Hope this helps.

Good luck.
