Re: 16.04 Long Term Support
Xubunut is more than just a different desktop - the intention is to make the whole system run well on lower-powered hardware. Whether or not in practice this just means its the XFCE desktop on the same underlying system is a matter of discussion.
As someone already pointed out for LTS one of your best choices would be MINT with XFCE.
And as any fule kno, the MINT project is a dervative of Ubunut focussed on the most recent LTS.
