What do you think is the best Linux desktop distro these days?
For hardware it seems like the higher-end Dells are the winners. I have a co-worker with one (runs Windows) and the hardware is excellent. He has some issues with the TPM and firmware but it seems like stuff that would not be a big problem in Linux.
These make it easy to set up a simple system with few moving parts, which is fast and doesn't break. I just a tiling window manager (xmonad), a terminal (urxvt), a browser (firefox with vimperator) and emacs.
And Nix-style ones, NixOS and GuixSD, are the future. Declarative system configuration and package definitions. Non-destructive changes.
In terms of laptops, I'm really fond of Xiaomi Air 12 M3. Fanless, really good quality, cheap and all stock Intel components. So it just works.
