Hi, According to me it lies majority on your interest and objetive in life. Like if you are interested in Finance & Audit do CA, If you are interested in Cost Accounts do ICWA.

CA- Chartered accountants are sought-after professionals in specialised areas of accounting, auditing, corporate finance, corporate law and taxation. A CA also acts as a business advisor by preparing financial reports, helping the business to secure loans, preparing financial projections and determining business viability. As a tax advisor, a CA helps businesses and individuals to comply with tax laws.

ICWA- As a CWA, you will maintain and scrutinise statutory books of accounts, prepare cash budgets, cash flow statements, do cost management planning and determine costing policy for companies, besides advising on investment and profit-planning. Good computing skills is a must for rendering services efficiently.

I have given you work roles for both, accordingly you can decide.

Good Luck.
