Top 12 Linux Distros For 2014

1. Ubuntu - Ubuntu is a Debian-based distro that uses Unity as a default desktop environment. It’s one of the most popular distros around, and it improves with every release. The latest releases have been quite polished, and have been optimized for desktops, and multi-touch devices such as trackpads and touchscreens.
2. Kubuntu - Kubuntu is an Ubuntu derivative that uses KDE instead of Unity as the default desktop environment. Beneath this, it is essentially the same as Ubuntu and is released on the same schedule.
3. Mint - Linux Mint was designed to be an elegant, modern distro that was easy to use, yet powerful. It’s based on Ubuntu and Debian, is reliably safe and comes with one of the best software managers. These days it’s one of the most popular Linux distributions around, claiming to be the most popular home operating system after Windows and Mac OS.
4. Deepin - Deepin is an Ubuntu based distro that has built the Deepin Desktop Environment (DDE) to appeal to newer Linux users. In fact, we highly recommend new users give Deepin a go. It’s stylish, simple and intuitive, featuring one of the best system settings panel displays of any distro. Deepin also features its own applications, like DMusic, DPlayer and the soon-to-be-released DTalk.
5. Elementary OS - Yet another Ubuntu-based distro, Elementary OS has differentiated itself superbly since the release of Elementary OS Luna. It features beautiful, simple default apps that follow the OS’s aesthetic appeal, such as Geary for email, Midori web browser, Maya calendar, Totem movie player, and the Noise music player. Some of the default apps were developed in-house in order to meet expectations.
6. Zorin OS - Zorin OS has been designed specifically for newcomers to Linux, with a look and feel that is all about making a good impression and easing the transition from Windows to Linux. The Ubuntu-based distro features, apps that will be familiar to Windows users, and makes it easy for users to run the Windows apps they still need. Zorin OS 9 has been built to be a lot like Windows 7, hoping to get some new Linux converts from those leaving Windows XP behind.
7. OpenSUSE - The OpenSUSE distribution is a general distro for Linux built by the OpenSUSE Project, aiming to be both a great beginner distro and something that appeals to experienced Linux users. OpenSUSE comes with YAST, an administration program that controls installations, package management and more.
8. Fedora - Fedora is an innovation-focused distribution, with a short life cycle that lends itself to leading-edge software. It uses the GNOME desktop environment by default, but users can easily switch to KDE, Xfce, LXDE, MATE and Cinnamon, among others. Custom variations of Fedora, known as Fedora spins, are available for users with particular needs.
9. Xubuntu - Xubuntu is an Ubuntu derivative that uses the Xfce (XForms Common Environment) desktop environment, meaning it is elegant and lightweight. It’s great for laptops and netbooks as well as desktops. Because it is light and uses few system resources, it is perfect for older computers.
10. Debian - Debian is an older Linux distribution which comes with the GNOME desktop environment by default, and it’s much-loved for both personal computers and for network servers. However, it’s also available for FreeBSD and work is in progress to support other kernels, such as the Hurd. Debian prides itself on coming preloaded with over 37500 packages, and with simple utilities that make it easy to get more.
11. Korora - Korora was originally based on Gentoo Linux, and evolved with the aim of making Linux easy for newcomers, but also useful for experts. It comes with a choice of desktop environments, including the Cinnamon, GNOME, KDE, MATE and Xfce desktops.
