I think it depends what your motivations for installing Arch are in the first place.
Things installing Arch will not do for you(coming from EndeavourOS):
- Make your system faster/better/more efficient
- Be practically different in a measurable technical way
- Give you some secret Linux knowledge
Someone else recently said this and it seemed very true to me:
all I’ve ever learned from installing Arch, is how to install Arch.
What does it take to install arch?
- The ability to follow well documented instructions
- The ability to partition your disks with minimal guidance
- To know which timezone you are in
- To understand which locale you want to use
Of course, if you are a beginner, those instructions may be a little overwhelming, especially if you lack patience. Disk partitioning without a parachute is probably the most daunting part, especially since it is basically the first significant task.
To me, what is actually interesting is not installing Arch, it is what happens after the install. In most cases, once you finish an Arch install you are left sitting at a TTY without a network. From here you need to figure out how to get the network up and running, create users, install/configure a DE/WM and DM, etc.
None of those tasks are particularly difficult but if you don’t know how to do them, each will take patience and research. Even after you do them, you will inevitably notice something you missed and needs to be added later once you start working with the system.
To me, what building an Arch system up from the bottom teaches you is less about Linux and more about basic qualities like self-reliance, patience, the ability to research things and the value of trial and error. I believe you will get more benefit from this process once you have enough Linux base knowledge to be able to process all the information that you will need to build up and Arch environment effectively.
Back to the original question, “Is it worth it?”. My answer is yes if you want the adventure and see value in the journey. Otherwise, if you are more focused on results of the install, it probably isn’t worth it.
Either way, if you do decide to do it, I would recommend trying it out in a VM first.
