I'm not sure about employers perceived but i guess they are the same.
They are generally similar but Finance is a lot more quant than F/A.
In Finance, you have to do some calculus, statistics and some derivations(But not as much as RMFE where they go much deeper into derivation and pricing derivatives).
In f/a you have to do more on corporate finance, accounting and financial ratio.
The different in core modules(The content of derivatives modules in finance and f/a are different despite they have the same name)
For Finance: Mathematical finance (Some stochastic calculus, some use of matrix and option pricing in discrete time)
+ derivatives(for finance)
+ Empirical finance ( Application of maths models for real world eg. GARCH, ARCH, AR, MA,)
For F/a Advance corporate finance(Deeper than corporate finance for MSc Finance)
+Derivatives(for F/a which involve less maths)
+ corporate strategy
The electives are different too. I guess Finance have to choose 1 quant elective and the electives for f/a are less quant and more general.
Might be just 2/3 modules different but it could mean a lot for some students in term of difficulty.
If you are good at maths(Calculus, statistics and know some knowledge in financial market) , you will be fine for finance course.
But i think you might be more suitable for f/a because you did business for UG.
All in all,it depends on your career goal. Finance is more on financial market side whereas F/a is a more on corporate or IB side.
P.S. I think it is harder to get an offer from MSc Finance compared with MSc F/A.
Hope it helps and good luck!
