I have always liked XFCE - always preferred it over Gnome, even the old, recently much lamented version.

Apart from liking XFCE as just a nice a desktop, I have found it useful:
  - for remote working over the Internet with VNC (reasonably responsive)
  - for virtual machines (used for testing on a desktop machines, not for virtual servers)
  - for old machines with little memory and fewer MHz.

I've tried LXDE (I really have - a year now) and I will never like it as much a XFCE so I'm returning to the fold.
