RE: APC Props?
I agree with your statement APC v MA, but, the APC is a more rigid prop and once up to speed will not flex like the MA will. From my understanding of it the flexing MA will give reduced thrust due to the fluctuating pitch.
As to the original question APC props at the price are prob the 'better' choice, but there are far superior props than APC you just got to PAY for them.
