Today, i set up my first pure-Arch environment and I can say,
It's freaking awesome.
Sure, its more difficult to use than Ubuntu, but damn, its really just the system I want.

good for you!

Nice, I want to do that soon. Do you have a good walkthrough to recommend?

I used the instructions on the official arch-website and this link https://linuxhint.com/setup-luks-en...
For full-disk-encryption.
Everything else is not that difficult,
Just don't forget to install network stuff like dhcpcd or net-tools ,
While you're in the chroot-env,
Else you won't have internet access in your new system.
