I have. My machines boot reliabily, my unit files work almost unmodified across my centos machines and my Ubuntu laptops.

I no longer have to learn a three-dimensional grid of init systems (init system, distro, distro release).

If this isn't a positive experience...

Systemd requires a small initial study effort in order to be understood.

If you're unwilling to do that kind of things (is: reading the fine manual), you might as well go buy a macbook.
