With this option, how often do you update the master image (Windows/plug-in updates, etc)?
When you perform the same steps each time (clone the updated machine, sysprep, domain join, then snapshot)?
Whilst this seems more... the appropriate way... it seems a bit annoying to have to wait on sysprep, and the windows automated setup - especially if you test and find out you made a mistake of some kind with the profile/update you installed!
