A Debian-based distribution worth mentioning is AntiX. It is 100% compatible with Debian, so everything that works under the original Debian, will work on AntiX too (SMXI-script for example). It is actually based on Debian Testing.
Only 32bit-versions are available, and by default they come with IceWM and Fluxbox as window managers. AntiX is primarily for older hardware. But you can install whichever window manager or desktop environment you like, you can use the official Debian-repositories, at least that was possible until version 11, now they are at 12.
It is a rolling-release Debian, which made it very interesting for me. Otherwise I don't have any stability issues. As with the original Debian, one should have some knowledge of Linux systems when using this distribution.
The guys on their forum are really helpful, even when asking newbie questions
