I have seen so many times that systemd is insecure, bloated, etc. So i wonder ¿does it worth to switch to another init system?
Short answer: if you’re asking this, then it’s not worth it.
Long answer: Ditching systemd in favor of something else is usually an act of experimentation. Folks that do it usually have had a negative experience with systemd, be it in its usage or from a problem they had that prevented them to boot their computers due to the tightly-coupled relationship between mainstream distros and systemd.
Also, preference is involved here, so you might prefer to assemble your system with independent pieces instead of a full-blown suite like systemd’s. You might also not like systemd’s UX so, as a user, you end up wanting to try something else.
