boxes is great, if you just want to try a distro and are already on linux.

there are distros that run on debian sid, if you prefer debian as a distro, but want a more up to date experience.

im running pika os, because it offers up to date gaming tweaks, but doesnt force you to update as often. keep in mind: that os is not something i would recommend for a environment where stability is the goal, because there are only a few maintainers. its just an example of debian sid!
