Have you ever used/considered using another rolling release? If yes, how would you compare them to Debian testing?

Also, are there any parts of Debian testing that is not rolling (i.e. OS version number or some package versions like kernel or Node.js)?

I've always used Debian since I discovered it via Knoppix (which was my first Linux distro, Cygwin was my first Unix distro), I initially used Debian unstable but downgraded to testing some years later as upgrading testing often is smoother than unstable. I've never considered even trying any other distro. Everything is rolling, except unmaintained software, that just gets removed from the distro when other faster rolling things change incompatibly.
