Low resource footprint — smaller than EndeavourOS on my laptop. Stability is fantastic. Bookworm practically just came out, so the packages are all much newer than they were in Bullseye, making it a viable option for someone who wants an uneventful Linux distro that fades into the background and lets you get stuff done.
Definitely my choice for running on server, not so much for desktop but for server Debian has fantastic stability and good enough support by 3rd parties
