Long Exposure vs. Stacked Exposures: Which produces higher noise?

My experience has been lots of 30 second exposures has way less noise than a 2-4 hour exposure. I generally use ISO800 or even higher at something like f5.6 and then stack in Photoshop. Another advantage of this method is if someone shines a light, light a car light in a place you never estimated a car would be, using the inverted brush you can paint out the offending lightened area.
I generally use something in the foreground for the image to stand on and lighten it with a flashlight or by taking a picture right before total darkness, when the sky is a deep blue. That is the base image, then I stack totally black night shots on top of that. For instance if darkness is at 2100, I might take and image at 2030, then start taking multiple shots of stars at maybe 2200.
This has been successful for me.
