A few days ago I switched from Ubuntu (Unity) to Manjaro (XFCE) Linux.
Manjaro is an Arch based distro, but with a graphical installer.
Like Arch, it’s a rolling release distro, which is very neat, because with the updates, the distribution also upgrades (you don’t have to do new installs anymore).
My pc responds a lot quicker now (my hardware is about 5 years old)…
I can recommend it to everyone!
