The DE is pretty frugal in resources, Thunar is not a bad File Manager, &c.
I have it on 4 of the 29 Distros I have on this Dell Inspiron
Only problem I have with it is that on at least 2 of the 4 (and same on another computer that has 50 Distros, not sure how many Xfce) - I like an enlarged cursor as you can see, and quite often it does not hold the settings beyond a few boots/reboots.
In the case of this rig, it is with Linux Mint 19 'Tara' and with Peach OSI.
I try different WM, fluxbox initially, so I think that Xfce is good, simple and clear; althought I'd like KDE (It's big if you have high resources). So Xfce must moving to gtk3 to nice look, but QT beat Gtk.
On Internet I saw some users to using fluxbox and similar, depsite haing an hight resources.
