Hi Ameer,

Well, it depends on your interests, both of these are very great branches will much of money. But in the case, you have similar feeling for both than,

• Aeronautical is a rare branch available in less number of colleges, so competition would be more tough while Architecture is available more easily.
• Aeronautical have greater packages than Architecture.
• Usually fee of Aeronautical is more than Architecture.
• There are more wide range of jobs for Architects while Aeronautical Engineers can do a specific job only.
• Lastly, Aeronautical is 4 year course while Architecture is a 5 year course.

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!
