In comparison to CS ,CA is more practical .In CS law is of main focus whereas in CA numericals is given more weightage.

Both have practical component. CA is numerical and CS is theoretical.
A student should go for CA if the student wants to make his/her mark in accounting initially. Because later at the last module of the exam, you will have so many subjects which will allow you to choose any domain of finance you like. But first you need to be exceptionally good in accounting to clear the first and second module.

A CS is someone who will take over the corporate governance of the company. S/he will be a master of corporate laws and practice and will be able to act as a direct advisor to the board of directors of the company. To pass CS, you need to have special liking for Law and how it works in company perspective.

So based on both interests you will have to choose which one you want to make your career in.

Because the prospects are not the same. So don not get confuse.

Good luck.
