One of the main differences I know of is that zooids are capable of independent movement within the larger organism. blastogenesis or budding is an asexual reproduction process where cell division is repeated at a specific site and these buds develop into new individuals that are still connected to the parent until fully mature. Not sure if this answers your question fully.
