I’ve just bounced into voidlinux and I’m very impressed by how complete* it is and how snappy. So that’s not a very objective measure, but my (old) battery life has jumped from 1.5h on fedora-38 to 2h+ under void (very similar workload). I think that’s an indication of how light-on the hardware the OS is - perhaps it’s because it’s not running systemd. If you’re looking to squeeze more out of your hardware, take a look at void!
the only thing missing from my manifest is mythtv - firefox, libreoffice, emacs syncthing etc and it’s all the latest
