What is your favorite OS and why?

Personally I like Vista and 7.  I like the features and once all of the vista warnings are disabled it seems like a nice os.  Also I enjoy Ubuntu and how customizeable it is.  What are your thoughs on all of the diffrent OS's and what do you think needs to be improved?
