Hi Lav, 

I answer this is the tough question for you in yourself, 

But i would suggest don't follow anyone & listen your heart .

If your good at computer Go for Computer enginnering 

Chemical enginnering if good in chemistry

the ans is just that no one can give perfect ans on this, follow what your heart says & follow your dream because in enginnering very feild has their own scope & career too

best of luck 

thanks
