Cinnamon is a fork of GNOME. Though the current GNOME (version 3) resembles the Mac OSX setup, cinnamon closely resembles a Windows setup. This is my environment of choice and the most recommended for the person switching to Linux from the Windows environment if they want to keep a familiar computer setup.
I like the cinnamon desktop because it is clean, elegant, and intuitive for a Windows platform user. The extra features such as Open as Root are useful for administration, and the advanced features in the Nemo file manager are very useful for most folder tasks a user may encounter.
