What I could propose to you (if you decision is not already made) is to use
Brigantia, just to try it out, see how it works, play a little bit etc...
But when Trisquel Toutatis 6.0 is out (maybe before the end of the year ?..
but it is not so far from the release date in my opinion), then just format
Brigantia and install Toutatis and you will be good for a couple of years :D
I'll be honest... if Toutatis came with Gimp 2.8, Netbeans 7, a functional
version of Youtube-dl, Gnome-Shell 3.4 working (or at least Gnome-shell 3.2
without bugs), and a compiz without the snap window bugs.
I will (without thinking twice), use Toutatis as my one and only Distribution
until the next LTS is out (and you are hearing that from an Arch/Parabola
Gnu/Linux user :D).
