Ranked in these QuestionsQuestion Ranking
Pro Very Fast
Pro Only need 512mb ram
Pro Beta has been released
After about 6 years since the alpha version, beta has been released on Fri, 2018-09-28. Check here for release notes.
Pro Runs perfectly on old Hardware
Pro Supports non-free drivers
Pro MX Snapshot: lets you make your own distro
Can create your own ISO (snapshot) and use it either as live-session and install back when needed.
With the (pre-installed) Snapshot tool you can easily create an ISO of your running system and then save it to a USB (or other media) and use "your own" distro as a live session or install back whenever you like (even on a different PC with different specs with no issues). You can even give that customized ISO to friends (selecting "non-personal" ISO when creating the snapshot; thus resetting the accounts & passwords and Home folder etc.).
Also you can save that ISO directly encrypted via MX Live USB Maker tool. Again, you can install MX encrypted during installation with just ticking a box, no matter if it's the official ISO or your snapshot.
Pro Easy to use
Pro Easy install
Pro No systemd
Pro Very stable
Pro Based on Debian
It is based on Debian and not based on Ubuntu.
Pro Good MX Tools and Package Installer
MX Linux comes with its own set of tools called MX Tools, designed to make life easier for users.
Pro Live-Session boots fastest after Puppy
After Puppy Linux (which's aimed to run from RAM and which is smaller in size) the second fastest (head & shoulders) booting one (together with the sister project antiX) and also has the option "toram" to run from RAM. Yes, not only when compared to full distros, even far faster than small sized or tiny distros, especially when booted to "live-session", about 2 - 2.5 times faster on an old single core laptop.
Pro Can also be used as an emergency tool
It has almost all tools to repair non booting systems or recover files & folders and save them on a safe place. And when thought together with it starts quick on live-session. In addition, you can do these with "your own", customized distro (snapshot).
Con No one uses it
It's a very niche OS that no one uses.
It's still in beta and quite unstable. Making it unsuitable for developing applications of any kind.
Con Small community
It is important when developing to be familiar with tools that other developers use. You can make any utility in any language you feel like, but if it's in an esoteric language that no one can read targeting a small platform that no one uses, then it was just something you did as a hobbyist, not as a developer.
This is not to say that Haiku isn't a great operating system to hack around on. Just don't delude yourself into thinking you're doing it to get familiar with tools that you need to know to be a better developer.
Con UI quite different to other OSes
Con Remixed Debian testing
It's mainly a Debian stable with some recompiled/backported Debian testing packages.
Con Causes overheating on some hardwares
Other debian based XFCE distros- Xubuntu, Debian XFCE, Devuan leave small footprint on system whereas MXLinux uses too much CPU resources on same system.
Con 10s of media players preinstalled
Con Old software
Many software applications are older.
Con Longer boot time
Con Too much customization
Con Only one Desktop Environment
Con More than 50 tweaking softwares pre-installed
Con Includes non-free drivers
Con Installer and configuration tools are different
Installer and configuration tools are different and can take some time getting used to.
