Hi there. I am ACCA and my sister-in-law is CIMA. If you want to work in practice (as an auditor) you need to do ACCA whereas if you intend to work in industry in a manufacturing company CIMA may be better. ACCA is also suitable to work in industry in anon-manufacturing company.
CIMA is mainly management accounting which involves budgeting and forecasting and variances between budgets and actuals on a daily basis.
Personally, unless you intend to go into the budgeting side of thing with a manufacturing company, I would recommend ACCA as I would be of the opinion that CIMA will leave you with limited options.
