How does GNU Guix's resource usage compare to lightweight linux distros (Puppy, AntiX, Q4OS, Linux Lite, Mabox, and Arch) when using EXWM?

I am looking for a lightweight Linux distribution for development purposes on older hardware and considering GNU Guix (yes, I like lisp, functional programming, and reproducibility :D). My requirements are a system that is resource-efficient both in terms of memory and CPU usage. I'm planning to use EXWM (Emacs Window Manager) as my desktop environment, and here is my emacs config file , which is relatively modest. Could someone with experience in using GNU Guix, especially with EXWM, provide insights into its resource usage compared to other lightweight distributions like Puppy Linux, AntiX, Q4OS, Linux Lite, Mabox Linux, and Arch Linux? I am interested in metrics such as average RAM usage after boot, CPU load during typical development tasks, and responsiveness of the system. Any comparative insights or pointing towards benchmarks would be greatly appreciated.
