Main advantages for CRUX :
– fast (simple yet efficient boot scripts) and “keep it simple” principle (targeted at experienced users)
– contains only essential software (reduced disk space usage)
– good package manager with support for dependencies (prt-get) and BSD-like ports system (few but quality packages)
Some cons :
– kernel must be compiled during installation process
– being a source-based distro, compilations will take a long time on slower machines
– no support for native languages (but this is done on purpose)
