Ive noticed its has been any activity in their github for a longtime. https://github.com/dylanaraps/neofetch
There are a few more info that could be added nowadays like Display Protocol (Wayland/X11) and Display size. FastFetch does this but Neofetch is globally recognized.
Fastfetch vs Neofetch
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I switched to fastfetch because neofetch was abandoned as far as I know. Or it might be that development just slowed down. Also fastfetch is faster than neofetch, even if its only very slightly faster, its noticeable (and I personally find neofetch annoyingly slow). And as one can see in the comparison image from you, fastfetch provides more info by default.
Also the developers react and implement bug fixes or other features quickly (7 open, 403 closed issues): https://github.com/fastfetch-cli/fastfetch
