Hi
If you are good in studies and have cracked jee entrance exam and getting a good college like nit , iiit or iit then definately pursue btech and if you have not scored good in entrance exams but you definately have a passion for studying computer science then go for bachelor's degree.
After that you can go for msc or prepare for any government exam. As btech is more complex and if you do not pursue it with full focus it may not be very beneficial for you , that's the thing which happens with most of the students so choose the degree wisely.
Hope it helps..
