Among the many flavors of Linux, the Debian Linux-based Ubuntu is the distro that tends to receive the majority of mainstream attention. Interestingly, according to the ever-popular DistroWatch, much as Ubuntu has surpassed Debian in popularity, Ubuntu has been overthrown by its own forked distribution: Linux Mint.
Linux Mint is merely one of many Ubuntu forks. Whether Mint is actually more popular than Ubuntu is up for debate, but the important part is that the Linux community has taken the Ubuntu code (you know, the Debian c0de) and customized it to add new features, serve a specific purpose in niche markets, and to offer up unique twists on user experiences.
So while Ubuntu is generally a good choice, it might not be exactly what you need. There are many other options out there that are worth knowing about.
