Debian desktop environment

[Antonino Saetta <antoninosaetta95@gmail.com>]

Hi,

After my surrender to Jessie I've thought of moving on with Stretch.

Currently I've installed it through the net, no problems at all.

So I was wondering, why am I asked to choose (or not) a GNOME desktop environment, other than Debian desktop environment?

I thought that Debian is GNOME by default...

Also, what's the lightest desktop? Default, XFCE or LXDE...?

Thank you :)
