If one was to become a christian, which is the best denomination to join? Okay, your questions isn't quite as open ended but it is close. Personally I prefer freeBSD (which isn't linux at all, but it will be hard to tell a difference other than names), but there are many other choices. I like the port system which lets me do everything myself if I want, but knows what needs to be done if I don't. Their goal is to be a good server, so it is a good choice, but it does not do everything for you. Suse or Mandrake seem to be the easiest. I use Suse on one machine and I don't like it, because in their effort to keep things stable they do not update to bleeding edge versions of everything as soon as it comes out. In addition the automatic tools can be a pain if you want to maintain things manually. This is a consideration that obviously may not apply, and indeed might be insightful enough to push to you Suse. Slasckware is old, and popular. It is the easiest do it yourself system. Many admins like it because you know exactly what is in it - what you installed and configured yourself. A good systems for experts who have better things to do with their time. Debian is popular, but I can't say much about it, other than it has a reputation for being behind on everything, and being really strict about legal matters. Gentoo is for people who want to compile everything. Very bleeding edge, but you have to configure and compile everything yourself. A good system if you are serious about learning, and popular so it must be good for something else, but as I don't use it I don't know. If Gentoo isn't enough of a do everything yourself, there is also linux from scratch. IF you are expecting attacks, or running a firewall, OpenBSD is the only thing I would trust. They will sacrifice everything for security, so it is an experts only system. NetBSD runs on nearly everything, so if you want to run one OS that is your best choice. (if you don't run things like a Vax or Sun3s next to your PCs don't worry about it) Redhat/Fedora also exists, but I know nothing about it. It is popular though. There are many other choices. I know I left some out. I think I covered all the major ones. Now you need to try all the churches and find out which one God ... err.. You need to try them all I figure out which one you like.
