The "debate" about systemd is like the "debate" about global warming: all the people with any knowledge of the issue fall on one side, and the opposition consists largely of the ignorant and butthurt.

Systemd has won by being vastly superior to any alternatives. I suppose it's all right to use something else but the community has embraced systemd as the correct solution, and you lose community support and assume all the risk of breakage if you do not stick with systemd.
