1. I have a relatively old laptop (Pentium Dual-Core, T4200);
2. Its memory is OK(-ish): 4GB;
3. I never cared about eye candy and fluff, I always wanted the snappiest response available with zero visual effects;
4. I've narrowed down my choices to Xfce4 or LXDE (Ubuntu, respectively Mint);
Has anyone gone from one to the other? Which one has provided you with a better experience overall (meaning here not only the Desktop layer, but also the patches and general stability of the respective distribution)?
