Hey,

Sreenidhi College is a decent choice to go for in Hyderabad. Both branches are good in the college, though ECE is said to have better lecturers and research opportunities. The rare ECM stream is a mix of both Electronics and Computers and it can be a little chaotic to learn both the subjects. 

However, if you're asking based on placements, it is mostly software companies which visit the college to hire students. They usually prefer CSE/IT/ECM people since they have a better knowledge of the field of computers. But there is no hard and fast rule, many ECE graduates in out country end up in software MNCs. 

You may choose according to your interest as you have to spend 4 years studying it. 

All the best!
