basically you should take the one you re familiar with. also choose, after how used you are to unix systems
gentoo is for advanced users which want to configure everything on their own. its hard work but its reliable.
ubuntu is basically the opposite : its doing everything for you. best for beginners - BUT if you CARE ABOUT FLOSS / OPEN SOURCE PLEASE TAKE LINUX MINT DEBIAN EDITION as conancial (the company behind ubuntu) really isnt that well with the open source community (as there were some ...coincidences )
fedora is a good stable linux distribution, which WILL work IF YOU NEED IT :) its for users which are not completely new to unix. dont know much exactly never used it but its good for sure
and arch... i dont like to talk about that there are many fags out there, taking this shit serious. i dont want to get them wrong but arch has a shitty repository, as there is a really bad system for packages + it isnt very reliable, any update can break your system. try it if you want to learn, but for anything else than fun PLEASE dont care about it UNLESS you are really good at solving problems on unix systems
i prefer debian, unstable to be exact. it's good for some learning purpose, but will need somewhat advanced knowledge.
be sure to pick the right distribution, :) and visit distrowatch for further informations.
best regards from someone who actually cares about linux, not just yelling out a fucking distro name
