Do you find the APC props liable to break on landing? I have APC props on two other models and they sometimes don't survive a nose-over on the grass, depending on where the blade is positioned at the time. The PZ prop seems to be flexible enough to take almost anything!
I have yet to break a prop on my P51D, APC or MAS.
If you find yourself breaking props, some more practice and/or a smoother field will help. I've had lots of experience belly landing nitro and electric planes, and have gotten over most of my "rough landing" phase with them. The field I fly at is tightly mowed and relatively smooth. If you fly on a clumpy field, you'll certainly have more prop breakage problems. The MAS props are more forgiving than APC with prop strikes, and as you say, the PZ will take even more abuse. I just don't like the flexing and vibrating of the PZ props.
Use whatever works best for you. It's just a trade-off between performance and durability.
