Well, if you want a user-friendly distro, that would be LMDE.
On the other hand, LMDE is based on Debian testing, not stable, and so, in LMDE you may get more updated programs. The only thing is that you need to be patient until Linux Mint developers are done with the different versions of the main editions, the KDE and the Xfce editions so they can work on the next LMDE Update Package. They come after every few months and that's a long wait for people who want the newest updates almost as soon as they appear in Debian testing (or Jessie, as it will be named when it becomes the next stable version).
Now, Cinnamon has been forked from Gnome and soon you will be able to have in Debian or any other distro. Right now that is a bit complicated, but when it is in LMDE, you can have it there too.
I would go for LMDE if I get it right that you don't want complications and if you are not too anxious about having the latest updates as soon as possible.
