Less packages really doesn’t mean much in terms of how easy the system will be to manage. If anything, I’d say a distro with more, but pre installed packages is easier to manage because the maintainers will make sure that those packages will be as easy to work with and upgrade as possible.
That said, I’m definitely not going to stop you from trying Arch though. You can even get similar (or better) optimizations by using the ALHP repos and a kernel like linux-tkg or linux-cachyos for example, although the difference really is negligible in most cases.
Yup. This is basically aimed at the people who only know that integrated GPUs are bad and they need a dedicated card, so system manufacturers can create a pre built that technically checks that box for as little money as possible.
