PCM for me.

I care about my models ... and the people around me.

More reliable radio link (higher signal to noise ratio)
+
Predicatable failure mode (I know my model is not going to head over a crowd if I lose that tenuous radio link due to interference).

It's not about saving the model, it's about saving innocent bystanders.

Choose enhanced safety: Choose PCM, choose fail-safe throttle to idle (minimum).
