There are other pages out there claiming to be neutral overviews, but they generally just take a neutral tone while rehashing the same long-debunked myths and spreading FUD.
The specific thing I like about systemd is the init replacement. It's just so much better! Automatically tracking daemon child processes, even detached ones. Supporting all the different modes daemons work, so I don't need to write yet another damn clean-up-all-the-children function in a SysVinit script. It's wonderful.
But systemd is a lot more than an init system and I don't really have strongly formed opinions on those.

Another persons writings to read, for similar reasons, is Ian Sutton, who is the bloke who did SystemBSD:
I could probably do it, but in all honesty, the "debate" has been so spoiled that I doubt anyone would take it seriously. My relatively technical article about FreeBSD and launchd (which had only one error about where plists were parsed, a relatively minor gripe in the text) was near-universally misunderstood and derailed by commentators who went on rants tangential to what I actually discussed. Same with my init history article.
But, if enough people want to, maybe I'll bite the bullet. Not sure if I'd like to subject myself to it, but I think I might end up writing a rather long treatise if there's demand and I do go with it.
