Just use what your distro gives you, you shouldn’t have to care about these things.

To expand on this: OP, if you want to try a different init, you’re most likely better off switching the whole distro to one using that init. Unless of course your current distro explicitly supports many different init systems (like Gentoo). Don’t try to replace it by hand in a distro that expects to run on systemd, it’s a recipe for disaster.
