No beating around he Bush: For some one who has a little knowledge of Linux, the highly recommended is Ubuntu. For the person new to Linux, the second highly recommended is Linux Mint (Ubuntu Remaster). The underlying operating system of all Linux distributions are almost identical. The difference in Linux is cosmetics, What Desktop Environment They are running, what programs and software are installed by default and if some one decides to include eye candy, bells and whistles from the repository file system and if they choose to install and include Compiz Fusion so it will use 3d graphics and rotating cubes which you rotate to see what programs you have running. Cosmetic affects. Every Linux can do just about all the same thing as any other. The user customizes the Linux to be their wants and desires. You in reality there is no best, it's just a matter of preference and opinions of a user. If you are a serious Gamer retain Windows and use a dual boot system. You get the best of both operating systems and they actually compliment each other by compensating for what one may or may not have available. All six of my computers are dual boot with different Linux Distributions. Linux wise there is not enough difference between the Linux I am using.
