SPI serial flash uses a small 8 pin part. Parallel flash uses a 32 pin
part. Do you really want to route all those signals to a much bigger
part for no real benefit?

SPI flash takes less board space than parallel port flash. So it can
reduce overall cost and size of a project. But it's slower since you
only
get 1 bit at a time versus 8, so it takes longer to wake up. Depends on
what is more important for your application.
