Which is a better branch in among obg, derma and psychiatry?

I was unable to decide on a single branch and ultimately zeroed in on these three. Derma is a difficult branch to get so most probably i will have to choose among the other too. I really want to pursue psychiatry but what are the job prospects in the future in this branch? And for the other 2 branches as well?
