When comparing Kubuntu vs OpenRC, the Slant community recommends OpenRC for most people. In the question“What are the best rolling release Linux distributions?” OpenRC is ranked 36th while Kubuntu is ranked 45th. The most important reason people chose OpenRC is:
OpenRC follows the UNIX philosophy of 'do one thing and do it well', while it's true that it has more features than sysvinit, it does not stay away from its primary function with unnecessary added features.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Full featured desktop environment that is actively developed
Unlike some abandoned, unfinished distros, Kubuntu is up to date and offers a fully functional desktop environment that targets workstation users.
Pro Stable as hell
Super stable, never crashes.
Pro Good hardware recognition
Pro Everything is highly customizable
Pro It also has paid technical support available
Pro Comes preinstalled in several laptops and desktops
Comes preinstalled in several laptops and desktops. (Tuxedo, Slimbook, laptopWithLinux.com, Kubuntu Focus, Vant and other companies).
Pro An outstanding number of packages and PPAs, backports PPA
Pro Kubuntu Focus Suite provides highly tested, curated ecosystem for pros
Pro Very stable
Kubuntu is very stable, you can easily install the appropriate Nvidia drivers for your machines, and not have dependency problems whatsoever. KDE offers a great user experience, and Dolphin is a great file manager.
Pro Customizable
You can easily adjust the workspace to your needs.
Pro Light
Pro No feature creep
OpenRC follows the UNIX philosophy of 'do one thing and do it well', while it's true that it has more features than sysvinit, it does not stay away from its primary function with unnecessary added features.
Pro Extremely simple
All configuration is done via shell scripts and symlinks. Shell scripts can then use various specialized utilities to ease the development of init scripts.
Pro Fast
OpenRC builds on top of sysvinit and adds some more useful features (like parallel booting) while still the simplicity that sysvinit is know for. Because of this it generally boots faster than other init systems, especially when parallel booting is enabled.
Pro UNIX-Like
Does one thing and does it well.
Pro Less dependency creep
Using OpenRC does not lock in a distribution by providing specific NON-POSIX extra services which programs then would rely on.
Pro A very balanced compromise
Basically OpenRC doesn't replace SysV init, but rather works with it, providing features that SysV is lacking while taking advantage of its benefits. It's also used by a fair amount of reasonably popular distros and is well supported and developed.
Pro Very efficient on system resources
Uses multi-core and ram very efficiently.
Pro Portable
It can be ported to other UNIX and UNIX-like operating systems.
Pro Flexible and extensible
I can add a new startup script for most cases in under five minutes. The ability to quickly insert new applications into the system is a big help.
Pro Not bloated
Pro Deterministic
It always initializes a system the same way; if OpenRC booted and ran a system properly today, it will boot and run properly tomorrow, and the next day.
Cons
Con Often unstable
There have been several bugs reported. Some of these bugs are: shutting down randomly, refusing to boot, refusing to shut down, menus may act strange, icons may disappear, etc.
Con No socket activation
OpenRC does not have socket activation yet. It will be added in the future though.
Con Not widely offered across distrubutions
From Distrowatch, only ten distributions (of which 8 Linux, 1 BSD) officially support OpenRC, and offer it through their standard repos.
