Hello Spigot! I have seen a few people argument about which OS is best, and some people asking about switching from windows to linux, so I decided to make this guide. This will be a brief summary of the major distro's to choose from, and a conclusion with my favourite picks. First, the obvious: CentOS CentOS is often recommended as the "Professional" distro to choose, and in a lot of cases, it is. CentOS focuses primarily on providing interprise grade software and being stable, at the cost of being less cutting edge. CentOS is generally considered less intuitive/user-friendly when compared to Ubuntu or alike, which I would agree on. - User friendliness: Medium - Stability: Very High - Cutting edge: Medium - Security: Medium / High Fedora I wanted to talk about Ubuntu after CentOS, but Fedora is simply so interesting it got second spot on the summary. Fedora is similar to CentOS, but provides a larger, newer software and is bundled with SELinux enabled and configured by default, making it a much more secure system than any of the other candidates. Fedora is generally as user-friendly as CentOS, except you'll need to understand SELinux. - User friendliness: Low - Stability: High - Cutting edge: Medium / High - Security: Very High Ubuntu Ubuntu is often a controversial topic in server hosting - some would claim it is unprofessional, others would claim it to be a secure choice due to it's very large and frequently updated repository. Ubuntu is the most resource intensive distro of all the ones I am comparing, but still far from enough to make any actual difference. Ubuntu is a very user-friendly system, making it a good choice for new users. Ubuntu's security is usually considered lower than most other, due to it's large amount of bundled programs and network daemons. - User friendliness: Very High - Stability: Medium - Cutting edge: High - Security: Low / Medium Debian This is one of my favourites. Debian is very similar to Ubuntu, but aims more at being stable and secure. The stable debian versions are rock solid and really lightweight. One of the only downsides to Debian is, when compared to Ubuntu, it's software repository, which aims more at being stable than cutting edge. Debian is still quite modern in it's repository though, and is usually not far behind ubuntu, version-wise. - User friendliness: High - Stability: High - Cutting edge: Medium / High - Security: Medium / High Arch Linux Arch Linux is not suited for new users to Linux. Arch Linux is highly customizable, also in the more low-level parts of the system. Arch Linux is about as cutting edge as it gets, and is relatively easy to use, even if you aren't deep into linux. Arch Linux' forums are by far the best linux community I know of, and their wiki is the best documentation I have seen any distro have, bumping up it's user-friendlyness. - User friendliness: Medium - Stability: Medium - Cutting edge: Very High / Extremely High - Security: Medium / High Red Hat I won't talk much about this one as it costs money and is meant for huge enterprises, but I'll mention it. Red Hat's major upsides is extreme stability and enterprise software. - User friendliness: Very Low - Stability: Very High / Extremely High - Cutting edge: Very Low - Security: High Gentoo This is an odd one as well. Gentoo is meant for linux enthusiasts, pretty much any software you want needs to be compiled by yourself. This means that all the software you get is as new as it is possible to have it. It is however the least user friendly distro of the ones in this thread, and is definitely not recommended for a simple game server. - User friendliness: Very Low - Stability: Can't be rated - Cutting Edge: Extremely high / Can't be higher - Security: Can't be rated. Please do remember that security mainly depends on how you set it up yourself - the ratings given are my judgement on a fresh install of the system! Thank you for reading! Hopefully this has provided insight on what system you should choose.
