As I have said 80 seconds or 20 seconds are not hard numbers, just used as an example. It can simply be rephrased as 4x speedup. I am not sure how the uptime argument is relevant here.

Your last point seems argument for the sake of argument. We are in a technical discussion, not a religious discussion. I did not buy a 8-core CPU to wait extra seconds paying electricity bill for the unused CPUs to validate someones hatred for some specific init system. If systemd can better utilize my system resource and cut my waiting time, I am going to use that. My lost time is the real issue, someones irrational hatred for something bears no value to me.
