Linux is not something you want to use for media use. It is good at being a Internet server, like web, SSH, etc. It is ok at being a web browser/e-mail desktop. It is awful at doing media. It is just a reality of the people who develop it, the design choices made, and the lack of central authority for making standards.
There is no reason to try it for media creation, other than if you just want to try it. None of the programs compare to what you have on Windows, and the experience will be a bit difficult at best and exceedingly frustrating and impossible at worst.
Maybe it'll change some day, but no time soon.
