While Void isn't exactly under rated ( it is very highly rated on distro watch for one ), for someone looking for a systemd free distro or a light weight one in general, it is a decent choice. The repos aren't as broad based as Arch but they do have newer versions of the software that they host.

I could be wrong, but aren't Linux Mint and Pop OS ultimately based on Debian? (Mint is based on Ubuntu which in return has a Debian base). Debian was my main entry way to the Linux world and there is a reason why so many distros are built on it. Very old as well (not as old as Slack ware but Slack ware isn't exactly noob friendly).
