#2 Fedora 15

Best suited for: Experts

Although Fedora pertains the same features as Ubuntu, the rampage approach with no compromise is what make this OS unique. With mind blowing features like good hardware support, revamped desktop look, this OS clearly is the best choice for experts across the globe.

One of the notable features of Fedora is its Gnome Shell. Gnome Shell is similar to Ubuntu’s Unity, where it brings uniqueness to the table with animated transitions and launch bar and application bar.

But experts still feel that Fedora needs more improvement as this OS still suffers from stability issues. Because of that Fedora is considered to be a pretty hard OS in installing, as compared to other software’s. But still these issues wont back this trail-blazing OS down, as experts consider it to be the best with its developed environment, libraries, configuration files and kernel headers, considered to be the best in the business.

Summing up: Uncompromised fusion of regular and corporate productive attitude.
