MS or MBA or MCA or Msc ???

I have been thinking a lot about these four post graduation degrees,i.e MS, MBA, MCA(masters in computer applications) and Msc(masters in science).I am a student currently pursuing BCA(bachelors in computer applications) from India.I have known MCA is not valued…
Knowing hard-core technology and its working interests me.I mostly remain confused about the life after graduation.Your suggestion will be greatly appreciated.
