Hi Aarnav

To decide which is better You need Proper Criterion , On the basis of Different criterion some are good in something and bad in something, If You consider job opportunity as a fresher just after graduation then Computer science and Engineering is the best Choice, But the bad part is that IT industries regularly replace old employees with new one unless You are very Productive and Plays some role in Decision making and also the job is more like Monotonous and You would not like after working for few years, because You will be continuously working with computers writing codes. While for aeronautical Engineering You will get a Job which is more diverse and interesting but then You have fewer chances of Jobs compared to CSE and also less Package so Now You can decide which is better But I would recommend You should go with the one which You like.
