I'd choose mine but I'm probably biased. :)
There's not much difference between the two although mine has replaced image
of Tux (the Linux penguin mascot) with that of Freedo (the Linux-libre
mascot) on boot but I understand that DNS plans to do that with his too.
One difference between the repositories is that I'd recieved some feedback
that some didn't want to be upgraded to the next major kernel release
automatically (like from 3.5 to 3.6 or from 3.7 to 3.8) because they didn't
trust major new releases to be stable yet. In response I created packages
that track with the releases of the supported branches so that those that
feel this way can then upgrade to newer release branches when they're ready.
You can also have a different package installed so that you are automatically
prompted to upgrade from one major release to another, if you don't feel this
way.
This isn't really a jxself vs. DNS debate, though, because I'm also involved
in the Launchpad project too as my time allows.
