Two are very different field. One is Aircraft Maintenance Engineering and another is Computer Science Engineering. Now how can you even compare? The genres are entirely different.

See the factor that can be a differentiator is the job related. AME will be a field job so you have to work hard physically and mentally in the airports where as if you go for CSE then it will offer you mentally engaging work profiles. Also CSE have more possibility of employments with good packages.

Now if you are interested in AME then just go for it because the mental satisfaction is the key to success. But if you have no such affinity and you just want a secured decent job then CSE can be great for you.

I hope my answer helps. All the very best for your future endeavors!
