Hello dear
Every branch has its own speciality you can not compare each other's .
Because you can get success ; fame ; money etc. In any field it will depend upon you and your skills.
And you should choose the branch according to your interest and your field.
So whatever you choose ; choose it wisely and carefully.
Good luck.

Hello Manasi,

There's no comparison between Aerospace and CS/IT. Both the courses are good if you are fit for this course. But when it come's to placement CS/IT offers more jobs that Aerospace Engineering. I won't discourage you to take Aerospace  Engineering as you can go a lot ahead through this field like you can apply for ISRO, DRDO etc.

All the best..
