DistroWatch published a review on Slackware Linux 15.0.

Slackware Linux 15.0

Slackware has a well deserved reputation for stability and for having a simple technical design. A design which frequently ignores modern approaches to system management. Slackware still uses a text-based system installer, has 90s-era approaches to package management, and prefers editing text files over graphical tools when it comes time to adjust most configuration settings. The distribution's official media does not offer a live desktop environment, though there is a community branch which provides live media for people who wish to test the distribution on their hardware. The project's official release announcement acknowledges this slow-to-change style, noting Slackware is just now adopting PAM authentication (something most other Linux distributions have used since the 1990s) and continues to use the classic SysV init software instead of systemd: "We adopted PAM (finally) as projects we needed dropped support for pure shadow passwords. We switched from ConsoleKit2 to elogind, making it much easier to support software that targets that Other Init System and bringing us up-to-date with the XDG standards. We added support for PipeWire as an alternate to PulseAudio, and for Wayland sessions in addition to X11."
