I almost thought I was back on Windoze the other day. I went to shut down my laptop and unattended upgrades stopped me. I have had this laptop for over 6 months and upgrade often so don’t get hit by that very often. Actually in the past I have always remove unattended upgrades.
Do you like and appreciate unattended upgrades, or do you remove it?
Absolutely not and habitually yes. 
On an LTS or very stable distro and most non-server installs it can be useful. I wrote a bit about it in these articles:
On my desktop and worklaptop: no unattended upgrades
Everywhere else: yes, I keep unattended upgrades
Hi, @Jymm

I may be in the minority in this discussion topic (at least, considering the replies, so far), but yes: I do like and appreciate unattended upgrades, in my laptop computers and Virtual Machines (that have “Ubuntu MATE” or other flavors of Ubuntu) and so I leave them turned on.
I need to visually observe updates to spot when things could go wrong … and intervene immediately when necessary.
I had one experience where I had to revert back to an earlier version of one package, because the newer version had an interface style which went “full-icon” (no text) which I have an absolute aversion to!
Since then, ALWAYS disable unattended upgrades.
I manually ask to mark all updates in Synaptic, then look up release notes for critical Apps to see what is impacted, and uncheck the ones I don’t want to apply.
I only use the “version freeze” when I am absolutely determined to never update an App, which is not often. For now only Chromium is in that category.
