- there is no general focus on being used at server or workstation - so can be used for either purpose. - For Ubuntu there is a separate image for servers (even if I guess that the difference is "just" in the default packages being installed and I can't change that during install process).
- I can choose my desired focus at installation (of being a server, developer machine etc).
- I liked the graphical firewall configuration tool more (over those available on Ubuntu).
- GSmartControl installed by default (will also be available for Ubuntu 9.10, Karmic Koala).
- I prefer yum over apt on the commandline because yum offers better output.
- There were more updates for Fedora than for Ubuntu, so I also had the impression that security updates were available faster - but this might be an impression only.
- My mobile internet stick (from "Three") was not working on Fedora 11. I tried a lot of manual operations to get it to work, but nothing helped. On Ubuntu 9.04, Jaunty Jackalope, it was a plug and play thing. Either less clicks than on Windows.
- A lot of applications I use are already available as package in the repositories (e.g. Freemind). Some of those I had to install "by hand" on Fedora. There are simply more packages available for Ubuntu than for Fedora (maybe because Debian-based), so less manual installations of separate rpms/debs not available in the repositories are needed.
- It was less tricky to get Skype to work (especially mic problems under Fedora). Although I got Skype to work even on Fedora 11, there were less manual changes needed on Ubuntu.
- There are a lot more cool applications in the repositories that I had not available on Fedora (at least not just with a few clicks). Just to give an example: With "Alien" it is either possible to convert rpm packages to Debian/Ubuntu packages - so you can get and install Fedora packages on Ubuntu as well.
- It seems that there is more Ubuntu on the clients than Fedora and it seems that the community is larger.
