I have the CFA designation. You are right - CFA and CPA are different. Obviously, it depends on your career goals as to which one you wish to pursue. CFA designation is very well regarded in finance industry, especially in investment management, investment banking, commercial banking etc. I have seen software developers with this designation and it makes it easier for them to get jobs related to finance. Just a word of caution. It is a long commitment - 3 years to be exact. But it does make a big difference to your resume...
