Fir bark vs pine bark in potting mix??

I don't grow orchids, but have used the bark in orchid potting mix as an amendment in potting soil for my house plants. I've noticed the fir bark is softer than pine bark, and pine bark doesn't break down as quickly. Pine bark is also much less expensive than orchid bark. Does anyone know the reasoning behind using the fir bark versus pine bark for potting house plants? Is one preferable over the other?
