It's very easy to build and modify everything, it doesn't hide errors under a rug (syslog messages are legible, coredumps not disabled by default and so on), so I feel like I can tackle any problem I encounter on it.
Also, if you're the type that carries their long .xinitrc/.Xresources/.profile around, it's more comfortable than the friendly linuxes which require you to re-do everything but in dconf.
