gollark: I prefer declarative service files, systemd integrates logging (so that `systemctl status` can show the last few lines of output) and generally has a nicer UI for monitoring and managing things (also, it seems that restarting services in OpenRC causes their output to just be printed to your terminal?), and actually that's basically it.
