I'm going to get a new (used) laptop soon. Which Debian release should I install at this stage of the release cycle, Jessie or Stretch? My current laptop runs Wheezy.

(I want as few bugs as possible, but also dislike the idea of having to upgrade in the near future.)

Also, is Xfce still the lightweight desktop of choice?

@stefanieschulte LXDE or other window managers seem more lightweight.
@yoxem Xfce and LXDE used to be similar a few years ago, but maybe they have taken different paths since then. I must admit I haven't paid much attention to how they evolved.
