SDHC as a workflow is a lot cheaper and simpler than P2. Then again, AVCHD is not as good as DVCPROHD. To be honest the AF100 could not be more different as a camera than the HVX though. If you are looking for a one-lens fits all run and gun documentary camera- the HVX is what you want. If you want to heavily invest in a variety of lenses and have much greater control over depth of field in your cinematography- you want the AF100.
