For the Default look you should check the official website www.ubuntu.com
It is highly customizable so one cannot say how it looks. It depends on how one customized it.
You can use Compiz for awesome effects and Emerald theme manager (you can even get aero like effects). You should also check cairo dock. It's really awesome.

Like crap... :D
I use very basic wallpaper & appearance + 0 effects or addons to keep video performance very low.
