With a few simple changes Linux Mint 12 would be the best.... again
Bottom Panel
Remove it completely . Put the "open program tabs" on the top panel.
Top Panel
Narrow the indicator icons
Replace username with simple LM logo
When mousing over the infinity symbol have the Windows & Application buttons appear there, in place of the infinity symbol
Put the search & Applications menu on the left
Other
Give the user the choice to "always show" dock (like in AWN, Unity, etc.)
Add right click "Launch on Log In"
and finally add some Linux Mint style
Of course, there are many more great tweaks, hide panel etc, but this could a good start.
