my opinion it that you dont have to try it out if you are doing this just for fun but if you are going to learn something through this exercise you should start from Ubuntu and then so far all of them they are all good in some specific features so good luck with it !!!
My favorite: Debian I started with Debian and for me it was a good experience and wise decision. It's fast, stable, easy to handle and serves all thinkable packages. But that's just my oppinion, it depends on what are your requirements. Easy-Starters are Linux Mint & Ubuntu (even based on Debian ; ) At the beginning I tried some Redhat derivates like Fedora and CentOS also, but those systems were not my flavor.
Ubuntu is doing a really good job and its expanding. And its from the Debian family. I think, Ubuntu will have a better market share soon.
For me,Ubuntu is Windows 7 from Linux.I use now Kubuntu because I hate Unity but my appreciation still remain.With these distros you can make everything..
Over the years, I've tried them all from Red Hat, Mint, Fedora, Open Suse, etc. + every Ubuntu iteration including Unity & non-unity distros. I finally happily settled on PClinuxos. It is especially easy if you are moving from Windows to Linux and the KDE interface is attractive and efficient. People seem to fall in love with Ubuntu (especially the critics who seem to push it) but I found PClinuxos to be much faster with less bloat. We all have are opinions and personal tastes so try all the Distros you can. The price is right We can all find one that is right for what we need and better than Microsofts entries . That's a no-brainer.
Have to agree about PCLinuxOS - it has the Broadcom wireless drivers already installed. All worked as one would expect for a newbie to Linux. Throw the un-tar at a newbie for wireless connection and he is through with Linux. My 2 cents...
I do all I have to do with Kubuntu,with nice interface Kde and easy and more customizable.As a Windows 7 user I can apreciate transprency glass is superior...in Kubuntu.
I run Fedora. Ubuntu is also good. I'm a Fedora fan. I run a Mythtv backend with Fedora 18. I've had very few issues with it. Most of them are in the first week of upgrading. I do bare metal installs each time, not trusting the upgrade mechanism. Soon, I'll upgrade to Fedora 19. I really like the way yum works rather than apt-get or aptitude. I only add on one third-party software repo, rpmfusion. I have had no dependency conflicts. The rpmfusion guys are great and will respond quickly if you see a bug with their RPMs. The issues arise from the fact that Fedora is bleeding-edge. I run into issues with the new major and minor versions of software sooner than others who are running Ubuntu. It can be a pain, but these things resolve. I do wish that there was more than a year of support. Third-party repositories tend to slow down their output for the older Fedora version after the new one gets released (every six months). I ran into this with new XBMC RPMs for Fedora 17 (the repo was stuck on version 11 when 12 had been released). I think that the Debian-based systems have the largest user base and therefore there is more support. This includes Ubuntu, of course. There is definitely something to be said for that. I've considered switching to Mythbuntu 12.04 LTS for that reason and also because there is support for three years. Upgrading every six or seven months can be a pain in the ass when you want the machine to be stable. I just know that I can upgrade pretty painlessly with the cheat sheet I've been working on since Fedora 15. I think there really is no 'best' distribution. I think that each must choose what works best for him. However, choosing a distribution backed by a large number of users or a strong company doesn't hurt.
I'm running Xubuntu and after all distros i've tried, it is the best for me. It's stable, has a gnome 2 feel, and because it's ubuntu it has a lot of packages. Zorin OS would be an alternative, but Xubuntu is more stable.
Am now trying the new Mint Debian Edition. A bit faster, using Cinnamon, than Mint 15 - although it is a bit more particular about propitiatory files. (ex: Can't as of yet use certain fonts, like Aerial. This doesn't call for an install as it will update system files as Debian does. So far, so good.
Greetins I am a LInux user I am running Ultimate Edition 3.4LTS It is the equivelent to Ubuntu12.04LTS only in a tweaked version.
