When comparing Xubuntu vs PsychOS, the Slant community recommends PsychOS for most people. In the question“What are the best Debian-based Linux distributions?” PsychOS is ranked 4th while Xubuntu is ranked 52nd. The most important reason people chose PsychOS is:
PsychOS is designed for older/lighter, 32-bit, i686 hardware with plans to go even further back with i486 (PsychOS486), i386 and older (PsychDOS), and so on and so forth as opposed to always trying to run on the latest hardware, not that it could in most cases anyway since 32-bit i686 operating systems will run on most x86_64 ones.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Great performance
Xubuntu is very fast and makes good use of resources.
Pro Quick boot time
Boots at about double the speed of most distributions.
Pro Comes with lightweight applications
Xubuntu is designed as a lightweight operating system and Linux distro. It uses XFCE by default and comes packed with XFCE applications which are generally pretty lightweight.
Pro Conservative, yet modern
It comes with all Ubuntu goodness but without bloat, a perfect mix between new ideas and usability.
Pro Customizable
Official distro of XFCE, one of the most customizable desktop environments. In XFCE you can create as many tasks bars as you need and configure every one of their elements and behaviours. You can also change any icon, font, color... etc. Literally there's nothing you can't change in GUI.
Pro Runs well on older, 32-bit hardware (i686)
PsychOS is designed for older/lighter, 32-bit, i686 hardware with plans to go even further back with i486 (PsychOS486), i386 and older (PsychDOS), and so on and so forth as opposed to always trying to run on the latest hardware, not that it could in most cases anyway since 32-bit i686 operating systems will run on most x86_64 ones.
Pro RetroGrab is really cool
It lets you install old software for use with emulators like DOSBox but run them as if they were normal programs from the normal applications menu.
Pro No fuss. Just works.
A lot of the programs are already set up for you. Just boot it and go. This is definitely one of the better SHTF distro's.
Pro QuickEdit
There's a yad-based tool you do not see on any other GNU/Linux distro in which you can simply right-click pretty much any file and then use the "QuickEdit" option to quickly edit small things about a file such as size if it's an image or video, convert the file, or even render the file if it's a Blender project. It's nice not having to open an image with GIMP every time I want to resize or convert something.
Pro The IceWM option looks and functions nice
Most GNU/Linux distributions that include IceWM as a desktop environment option don't do too much to it, if a t all. PsychOS seems to have a customized or themed version that actually doesn't feel you with dread and still uses many of the keyboard shortcuts from XFCE.
Pro Lots of command-line tools
Lots of command-line tools and I really like the CLIMax thing. It's a good tool to have if you want to spend time in the command-line but aren't that experienced. Also, it plays a quick, one-time ascii animation when you go into the tty for the first time.
Pro TONS of Thunar Custom Actions
PsychOS comes with a lot of Thunar Custom Actions, many of which as disabled, but they are there none the less; most probably just in case. Right-click on a DOOM WAD shows there's a menu item to play it directly using LZDoom.
Cons
Con XFCE development is slow
The desktop environment used in Xubuntu has not been updated in over two years and is developed at a snail's pace.
Con UI is pretty generic without customization
The default XFCE UI is pretty generic and sometimes ugly unless customized to suit the user's needs and liking. Customization in XFCE is easier than on Unity, but still hard for beginners.
Con Redundant
There is absolutely no reason to install it, since it uses the same package repositories as Ubuntu and you can transform any Ubuntu install into a Xubuntu install.
Con Bloated
Over 3000 packages by default including several package managers.
Con 7 package managers included
There should only be one.
