Mint has stayed away from transparent windows and other Windows-like bling. But there are Theme editors so you can bake your own.
Same thing with gkrellm (right side of my desktop), a very useful app but its UI is very ugly, so I tweaked my own Theme with a text editor in less than 5 minutes. I’d be happy to upload it if anybody’s interested.
Ububtu is the most advanced distro but has the W8-like Mickey Mouse UI, however you can install Ubu 12.10 then add the MATE desktop with instructions in http://mate-desktop.org
Lots of choices
