I'm trying to choose one Linux distribution for everyday use and to learn more about how the operating system actually works. I've already tried CachyOS and Kubuntu on my main PC, and I was able to configure both successfully, although the process was quite different.
Kubuntu initially feels more approachable because I have some experience with it from a home lab, and software vendors often provide Ubuntu packages first. On the other hand, Arch seems appealing because it encourages a more hands-on approach, and the Arch documentation is widely regarded as excellent.
Since I'd like to understand what I'm doing instead of relying on an AI whenever something breaks, I want to commit to one distribution and learn its tools, package management, configuration, and troubleshooting methods. I'm mainly weighing Ubuntu's stability, compatibility, and larger software ecosystem against Arch's newer packages and more manual approach.
What are the practical advantages and disadvantages of choosing each one for learning Linux? Would one be a better starting point for a daily-use computer, or does the choice matter less than simply sticking with a distribution and using it regularly?

Kubuntu and CachyOS are already giving you two different experiences, so you could simply choose the one that makes you more curious and stick with it. Kubuntu is based on Ubuntu; its main difference from standard Ubuntu is the KDE desktop, not the underlying system. Likewise, CachyOS is an Arch derivative. If your goal is specifically to learn Arch, installing plain Arch manually at least once can teach you more than using an automated installer, though you don’t need to reinstall manually every time afterward.
Either choice can handle everyday tasks, so don’t get stuck trying to find the perfect answer. Ubuntu-based systems are generally easier to start with, have broad hardware and software support, and offer a large pool of documentation and troubleshooting advice. Arch gives you newer packages and tends to make you investigate more of the system yourself, but updates can occasionally introduce problems and troubleshooting may be more difficult when the issue is new.
If stability and a predictable system matter most, Debian is another strong option. It has a straightforward package system, a huge amount of documentation, and forms the foundation for many other distributions. You can learn the command line, services, filesystems, networking, and system administration just as well on Debian or Ubuntu. The distribution matters less than whether you actively use the terminal and investigate how things work.
Learning Linux is more about what you do than which distribution you select. Use a virtual machine or spare computer for experiments, keep backups, read documentation, and understand commands before running them. Ubuntu or Kubuntu will let you build that knowledge on a working system without making every initial setup problem part of the learning process. If you eventually want a more manual experience, moving to Arch later is a natural progression; if you want to understand the system at an even lower level, Linux From Scratch is better treated as a separate educational project rather than a daily driver.
The biggest practical distinction is the release model. Ubuntu and Debian-based systems usually favor older, tested packages and scheduled upgrades, while Arch-based systems continuously deliver newer software. Choose Ubuntu-based if this is your main work machine and you want fewer surprises; choose Arch if you specifically enjoy following changes, reading update notes, and fixing occasional breakage. The AUR is convenient, but it contains user-maintained build instructions, so you should inspect them and treat them as third-party software rather than blindly trusting every package.
You also don’t have to use the AUR. The official Arch repositories are enough for many setups, and avoiding the AUR removes much of that additional risk and maintenance.

That makes sense. I’m mostly interested in understanding the underlying system rather than just changing desktop environments, so doing one manual installation could be useful.
