I have switched from LXLE back to Xubuntu on my Dell Latitude D430 and here's why: Firstly, none of the shortcuts I am used to worked in LXLE. Print screen, CTRL+ALT and cursor for switching between desktops, etc, none of those worked. Tab completion was missing too in bash. Oh and even though I added a battery applet in LXLE, sometimes it would still not start on login. All these little niggles drove me back to Xubuntu.
Xubuntu 14.04 LTS also feels much snappier than Xubuntu 12.04 did on the same machine. It feels so smooth and well thought out now. I found LXLE to be fairly well laid out but not as smooth. I also love the now default Whisker Menu, it's much more usable than the old XFCE menu.
Switching from LXLE to Xubuntu did not take long, I backed up some of my configs (.mozilla, etc) and did a wipe and reinstall, and I was up and running in about 15 minutes. I just had to reinstall VLC, xubuntu-restricted-extras and a few other apps and that was it. I've always generally stuck to LTS releases of *buntu releases, and Xubuntu 14.04 is truly excellent. Here's how my preferred desktop setup looks on my D430.
