Hello Ravi.

To be very much clear let me tell you that I am also a mechanical scholar.

I can tell you that both the branches are very good . You should take your call in this matter.

I can just tell you that ECE is relatively easy in comparison to mechanical. Placement of ECE is also relatively high , packages are approximately equal.

The only advantage with mechanical is that it is a very interesting branch if you have a little interest in it. Once you develop a interest in it you can surely do better in life.

Good luck.
