Ubuntu VS Other Linux Distributions
If you log into the command line of both an Ubuntu system and a Red Hat Enterprise Linux or Fedora system, very little will look different. There are common directories and utilities between the two, and functionality is fundamentally the same. So what makes Ubuntu different from other Linux distributions?
One difference is the installer.
The complexity of booting and installing Ubuntu has been narrowed down to a handful of mouse clicks, making many of the install decisions automatic based on assumptions as to what the average user may need and want. In contrast, a Red Hat system presents the user with many install options, such as setting up a workstation or server, individually selecting packages to install, and setting administrative options.
Another major difference among Linux distributions is in software management tools.


Pure Drivel
Ok, you expect Unoobtu fanboys to say incredibly stupid things - but comparing Unoobtu with RHEL - come on, that's like comparing a go-kart made from an old lawn mower to a Ferrari.
