Whether aerospace at IIT Madras is better or ECE at IIT Bhubaneswar is better this choice solely depends on your career goals, subject choices, and preference.
I also had the same dilemma and I chose Aerospace at IIT Madras over other departments for the following reasons:-

The aerospace course in IITM is a well-structured course. IIT M is also the top-ranked IIT in our country (NIRF Ranking-1). The placements for this branch have been consistent over the years. In the 2019 placement drive, the institute witnessed 70% placement offers with an average annual CTC of 16.1 LPA.
ECE at IIT Bhubaneswar is a new course as it was started in 2016 and the first batch will graduate in 2020. The syllabus of ECE follows the curriculum of IIT KGP and incorporates the latest industry trends. The infrastructure in terms of labs, faculty, etc. are commendable at IIT Bhubaneswar, but in terms of placements for this branch, it’s not as good as the aerospace branch at IITM. There are no past placement records for the ECE department but the overall placement rate in 2019 was 90% with an average CTC of 11.44 LPA.
While considering the branches individually ECE seems to be a better option than aerospace. ECE opens up a wide array of options, for example, manufacturing jobs, while the scope of the aerospace course in the niche. Finally, if comparing both the courses IIT Bhubaneswar’s ECE may offer good scope due to its traditional nature, but in terms of placements and overall quality of the course, IITM’s aerospace engineering is better.
