As per the latest stats, you will not be able to get admission in CSE at IIT Roorkee at this rank if you are from the general category. I think that you should choose EE at IIT Kanpur over CSE at IIT Roorkee because of the following reasons:-
Irrespective of your rank, go for CS at IIT Roorkee only if you are definitely interested in it. This is because CS is a field that requires commitment and is not everyone's forte. You will question the quality of professors here and feel that you are missing out on the fun-filled college life at IIT Delhi or Bombay.
No doubt, Roorkee has excellent CS placements with many tech giants and startups offering huge packages. But anyone who starts losing interest will find it hard to switch fields during placements. Very few Consultancy companies make it to the campus. The major ones don’t visit IIT Roorkee and so you will be missing big time.
So, only after thoroughly analyzing yourself, go for CS at IIT Roorkee. The placements offered will be great but you will have to invest your personal efforts a lot as the institute is a bit lacking. As far as IIT Kanpur Electrical is concerned, you will find great opportunities and campus life there!
