The debate isn’t even funny anymore, it ended completely IMO when Debian decided on systemd, despite heavy propaganda with wild promises about how amazing they planned to make upstart. Promises that were never gonna happen, and some of the problems they promised to solve, had been left unsolved by upstart developers for years. Some of them allegedly because they were basically impossible to solve in upstart, because the basic design concept is flawed, just like other init systems based on the System V legacy.
