There's a large list here: https://beucismis.github.io/awesome-fetch/

Sampling some of them, there seems to be a wide variance of how much they show, how shiny the image next to the info is, and what kind of info is shown (e.g. one of them shows stats on your git repo).

My favorite is pokefetch.

Greybeards just use cat. But really have no need to show off stats in screenshots anyways (:

Can confirm. I'm a graybeard, and I use cat pretty much exclusively to read this data. Sometimes I even pipe the output through text processing tools to isolate specific parts of the data dump.

(Not saying the higher-level tools like neofetch are worthless at all, just saying they aren't a part of my workflow.)

Of those, only fastfetch is a true neofetch alternative.

Neofetch itself is just a (faster) alternative to the original screenfetch

Here is a long list with a bunch more:

There's also fetchfetch: https://github.com/Blobadoodle/fetchfetch

Aww, I thought that was a tool to fetch (download) all the *fetch tools. Alas, it just lists all the ones you have installed.

I've been using fastfetch for ages, personally.
