2. ACA is better in theory. Many sub-members of ACA are members of GAA (the world's most powerful professional association alliance organization, the slogan is to serve the capital market), but ACCA is not; However, ACCA entered China earlier and is more mainstream, with rich learning materials and training courses, which ACA has not seen yet. ACCA and ACA membership can be transferred to each other, and ACCA membership is valid for 5 years. \
So aca is more popular.
