You must ask yourself what interests you. Choose a branch that is only allowed by your marks and cutoffs. That is the most serious error you can make. Without a doubt, the college from which you graduate is significant. What matters more is what academic records and experiences you leave with. If your grades allow you to choose between SC and ST in Swami, you will be eligible for many more colleges and branches. Even in KJSCE for EXTC. Yes, both colleges are excellent. You should pursue CS in Swami, but don't just enroll in colleges and branches because your grades and cut-offs allow you to. 

Allow yourself plenty of time. Make a decision that will benefit you and your interests in the long run. Don't get your seat confirmed anywhere until the last round of admission and vacancy until you get one of those you want to be in. the cutoffs for vacancy seats fall like anything at the end of admission rounds. students with scores of 170 and 120 have been seen in the same class.
