Hi,
First of all, decide whether your interest is more theoretical oriented or practical oriented. CA is the one who specialises in taxation, auditing and accounting, a majority of the subjects are practical. Company Secretary is a specialist of law, drafting and compliances. A majority of the subjects are theoretical. There's no such thing as easy or hard. Both are almost at the equal level and require the same level of hard work and understanding. Seeing working prospects wise, CA is much more recognised course among the masses and can start his own practice with ease, that's not the case with CS. However, with the companies act 2013 the job prospects of CS enhanced tremendously as compared to CA. Both have their own pros and cons. Decide wisely. Feel free to ask further.
All the best.
