Fedora is more compliant with Linux Foundation and LSB recomendations.

rpm is much better package managing system than deb based.

SELinux brings extra security, which most debian based distributions lack in the beginning and is rather difficult to install afterwards.

You can try Fedora easily with a bootable CD or better yet bootable USB-stick for some time, before deciding if you want to install or not. Fedora then can also install side by side with MS Windows. Fedora installation system knows how to shrink the Windows partition to fit Fedora in.

The easiest way to try and make a Live-USB-stick in Windows, is to download and run LiveUSB-creator for Windows. ~700 MB USB stick or larger needed.
