What's better ACA or ACCA?

This often turns into a big debate but I would say that either one would be great for your career.  They are both CCAB qualifications and just as difficult to pass (although ACCA is easier to become a student with).

The key is where do you work/want to work.

ACCA puts itself between ACA and CIMA in terms of content.  ACA is more practice/tax focused.

I am ACCA and work in an ACA firm.  There is an ACCA manager but the partners are ACA.  My brother works in an ACA firm and a director is ACCA.

I chose ACCA as it suited my study needs/committments at the time as the course providers are more flexible.  However if you work in practice I would give the edge to ACA just because alot of old school accountants/businessmen still perceive this as the only 'Chartered' qualification despite this not being true as every CCAB qualification is with a 'Chartered' body...

The largest accountancy firm in my area with 400 staff is an ACA firm but the managing partner is ACCA.  This demonstates the little difference it makes to ones career in most situations.

It's a bit of half a dozen of one and 6 of the other so go with what's best for your study plans and the culture of your employer.
