What matters is the most is interest.Don't think about placement both are good and have good placement if you are doing it with your 100%.Hope it works

Dear Naganad
I too agree with the Sohali. It's depends on your passion like you're very passionate about machines you can opt mechanical, if it's on electrical circuits you can opt electrical. But if you don't know what to choose. Then my suggestion is to opt mechanical rather than electrical because  it's not so complicated and you can easily crack that.
All the best

It depends on your interest...... both are good.... but it also depends on colleges also...... so for which college you are asking about?
