XWiki Operating System Support

Hello, I am a newbie to XWiki and wanted some information. As XWiki is written in Java, it can run on any O.S. Which O.S should be the best choice for installing XWiki. I am sure each of you has had his own experiences with Windows as well as Linux. So, how good can Xwiki be, if we install it on Linux or on Windows ? -- Regards Umair
