I prefer to be actively administrating my server, so that I know if something does go awry. If I'm asleep, it may be a few hours before I realize that an update broke something. On top of that, I clone my servers and test upgrades in a development environment as much as possible, before allowing an update to go live. As long as you're on top of the updates, a few days between automatic and manual shouldn't have much effect.
