I prefer APC due to the fact they are more efficient and produce better instant response in case of a emergency situation.
APC's are HORRIBLE for instant response! Most plastic (composite) props are bad, they are simply much heavier than a comparible wood prop. I've got planes that span 10x6 to 18x8, and run both wood and composite props at different times. engine spoolup is MUCH quicker on wood props, but your idle is also going to be faster. Overall, I tend to prefer APC's though.
