Which would be a bettor course in SRM main campus Electronics and communication engineering or electronics and computer engineering?

It would be a big, big gamble on your career. Join at your own risk.

The EEE department is fairly good. But, the Electronics and computer science is the new department under the faculty of electrical engineering. The teachers are not even familiar with it's syllabus very well. And what's more? In most of the cases, teachers of electrical engineering are going to take your computer science subjects as well!!

Some inside news for you, the HOD of EEE department was forced by the college administration to increase the number of seats in the E&Cs department, despite the concerns raised by him, regarding the substrandard skill of teachers in teaching computer science subjects. I

Infact, there's a shortage of professors in the EEE department itself! How are they going to provide decently qualified faculties for E&Cs?

Also, you are going to be the second batch of E&Cs. So, if you want placements, then your senior batch must get to its recruitment phase i.e. Final year, so that one can see the trend of placements. Their future is uncertain as of now. Since, no one can determine whether the companies would prefer a E&Cs candidate, but i am sure that the college placement cell will do its best, but still there's no guarantee.
