Suppose you’ve got an old PC - for arguments sake, assume a late 2000s PC with only 2GB RAM - which DE would you choose?
Note that whilst a simple WM + some lightweight apps might be a better option, to keep things simple, I’m limiting this poll to just DEs - and too ones which are still being maintained.
Also, in case you’ve voted for a non-obvious/“other” option, I’m curious to hear about your experiences on running that DE on an old machine - and why you’ve selected it over the more obvious choices.
The point is that LXQT and LXDE use half as much ram as Xfce. I’m not saying OP should use KDE.
