This is like declaring McDonalds burgers the best because small burger joints can't offer Burgers _and also_ ice creams, salads, chicken and toys for children.

If we're talking about init; there are actually better inits already available but you'll never hear about them (runit, for instance) precisely because you don't just leave systemd.
