There are reviews of many of the packaging solutions over at
APPDEPLOY, however, most of them appear to be way out of date
with the current versions.

Both of these are good products and both are probably overkill for most
small to medium size businesses. Quite expensive packages.
For many Admins they could probably get away with a much smaller
and cheaper package.
