its great in the sense it offers both glibc and musl, between using void and arch, I do prefer arch more; faster installation times and it uses about the same memory (on idle) as it would with void. in the end I chose arch Linux as I’m more familiar with it; I’ve been using it for 4 months now and there are specific applications i use that are easier to install and get on arch than with void.
as I continue to say, arch now is what windows 10 was 10 years ago, you have AUR, you have pacman. With some minor problem solving here and there, applications haven’t been easier to install on linux.

the reason browsers use so much memory is a result of JavaScript, read justfuckingusehtml.com to get more insight.
the browser I used that got the least amount of memory is emacs (eww). Sure it doesn’t have js but it is a literal goldmine of the best articles your eyeballs have layed on since 2015. the internet nowadays has become so enshittified I use eww just so I can get away from the dumbed down shit search results that come from these (clearly) money motivated outlets. Those MF have no passion whatsoever, they’re init for the $$$.
If you still want js, use qutebrowser, it doesn’t have extensions but at 300 MB it’s the best option out there, I do like the UI and overall navigation: it takes inspiration from vim/nvim and you can keybind shortcuts for specific functions.
