Unique? Personal favorite of mine: https://dyne.org/dynebolic/

Personally, my "I'm too lazy to build this from the ground up" daily driver is cachyos now...used to be Manjaro or Garuda, but I feel like cachy does the same stuff with less bloat.

When I feel picky and want to spend the time, void is my goto. Xbps is a fantastic package manager. Nix is worth running as a daily driver once (although guix sounds REAL interesting), but it's not for folks who want to avoid a steep learning curve. If you want something more gentoo-flavored, sabayon is gentoo for the lazy (and it bundles a binary package manager for those who are impatient xD ).

I know one guy who daily drove tinycore for a while. Same with puppy Linux. I couldn't get into beyond the occasional live boot.
