Do you use Windows? Then use Mint.
Ubuntu is an answer to a question that never really existed, which is, "How do we make a Linux brand that is different from the two other major OSes?"
Not to say there's anything (majorly) wrong with Ubuntu. It's just that the point of Linux is that you can make it whatever you want it to be. So the best method of selling Linux would be to show Windows and OSX users that they don't have to feel like a stranger using their computer if they switch to Linux.
And for people like me, you can throw in Arch Linux and build it from the ground up with XMonad and the barest of essentials.
