> Looking for a way to get a modern debian (something akin to non-LTS Ubuntu)
Not exactly sure what you mean by modern, but I'd recommend debian "unstable" (also called "sid"). Despite its name it's pretty stable. Normal debian stable releases are LTS style, unstable is where newly built packages show up first—so it will generally have the latest version of stuff and not be stuck a year or 2 back. It's basically a rolling-release style thing—I put in a little cron-job that does `aptitude safe-upgrade -y` every night to keep me up-to-date.
You can also use debian "testing", which one step back from "unstable"—packages are promoted from "unstable" to "testing" when if they've gone 2 weeks without a bug report of some particular severity (that I can't remember off the top of my head).
What's nice is you can have both testing and unstable in your apt sources—on my machine I set the priority on my testing higher than unstable so I generally get the testing packages, but I can grab unstable if I need to. I've been running this way for about 20 years now, and it seems the right balance of new but consistent.
