If you want to climb up the corporate ladder and potentially become a CEO one day go for MBA.

If you want to restrict yourself in a support function of an organization i.e. IT, unless you are working in a software house, then go for MCS.

What job you shall get after MBA depends on the quality of the institution you have graduated from. It is highly recommended that one starts his/her MBA after gaining few years of practical work experience.

The nature of my job is such that I meet CEOs/Presidents of commercial banks, FIs and industrial corporates on regular basis. I am yet to meet someone who is MCS only. However, many have MBA degrees.
