Been there too. The thing I disliked most, that it sometimes get stuck in some strange pose, without any reasonable way of remediation. And because it is so annoying to debug, reboot become the only tool do deal with it.

The sheer complexity of systemd created nasty feedback loop: it is too complex to be debugged; people prefer to reboot it; that keeps problems keep accumulating inside.
