It is easier for me to switch the PFET. I know these have somewhat worse
characteristics.

Another question: is it mandatory to put a special capacitor over the
power supply near the bridge FETs? At first guess I thought so, but
maybe it is a bad idea: it would worsen the effect of shootthrough, and
the load is inductive, so the load current won't have sudden changes
anyway?
