Hey aspirant,
You should choose only that branch in which you feel you are comfortable with. Because of course you won't want to waste your four years of life in studying something in which you are not interested.
Also, the colleges are preferred on the basis of one's priorities.
However if we see the placement statistics of both the colleges then highest package offered by svnit is 39 lpa and average is around 4-6lpa.whereas in Nit calicut the highest package offered is 50 lpa and average ranges around 7-10lpa.
So, on the basis of placement statistics I would suggest you to go for Nit calicut but as I mentioned above the choice should be totally yours.
Hope it helps
Good luck.
