Why do so many people install Arch if it's so difficult to install?

Because you learn how the linux components work with eachother while you are installing the system.

It's like doing housework by yourself. It's expensive, dangerous, slow, boring but makes you proud

I just see many Arch rants around here and I was wondering in what way is it better than other distros (I'm just a noob, I've only be using ubuntu for a year). Is it better somehow performance wise or just more customizable?

It's basically like blank canvas and you are the painter. It's freedom.

@jsframework9000 the main difference is, that arch is a rolling release system, so there are no major versions, but only the versions of the individual software you installed.

And biggest pluspoint: there packagemanager is called pacman :)

I tried and failed while trying to configure Nvidia drivers

@irene I would upvote 10 times if I could.

It's not that difficult. Look at the arch wiki, which is great Btw, and follow the steps... And that's it
