Mr. Amit you need to understand one thing that none of the professional courses are bad it depands on your interest.All the courses deals with Finance, Company law and taxation. Let me explain you
If you are planing to do CA your focus will be more on Accounting and Taxation and you will have to also undergo 3.5 years of articleship.Even under CA company law is a major part.
If you are planing to do CS your focus will be more on compliance part and you will have to deal with Company Law and Sebi regulations.Even in CS taxation,Finance and costing forms part of course curriculam.Under CS you have to undergo training of 1.5 years.
If you are planing to do ICWAi your focus will be more on costing and in this course also taxation and company law is very much there.Under ICWAI you have to undergo a training of 3 years.
My advise to you will be to first decide your interest. CA, CS, ICWAI are masters in their own field and in todays world you need to be updated whichever course you do.So dont worry just decide which course to do and just go and enroll for any one of them all of them are best.
