Vishal,

You have given different branches of engineering. To choose a branch totally depends on you and your interests.

But if I have to rate I would suggest you to take NIT Surat CSE as it is most popular branch of engineering and IT sector companies offers great packages like 40-50lakhs.

But if you take mechanical engineering you have good option of getting PSU after qualifying GATE. As NIT WARANGAL AND ROURKELA are very reputed many PSU visit their campus and hire students without GATE score and getting a government job is like getting dream true.  They give high salaries and you have to do less work.

So if you are interested in High packages and want to work in big cities or abroad go for SURAT CSE. If you want to get good government job go NIT WARANGAL MECHANICAL.

HOPE IT HELPS.
