CachyOS with NiriWM. Cachy is Arch with none of the install drama. The performance tuning makes it blazing fast on older hardware. Installs with no bloat.

Niri is superior to Hyprland in my opinion because it's a scrolling tiling WM that is super intuitive and fast.

For server workloads, however, not much beats pure Debian. It's stable, well supported, and has a huge package library.
