Under sysvinit halt and poweroff were the same. Under systemd 'halt'
halts the machine, whereas 'poweroff' first halts the machine and then
switches off the power.
I use 'halt' a lot to debug shutdown bugs, don't know if it has other uses.
Manually power cycling a halted machine is safe.

I can confirm what Tom is saying is correct, on my old slackware install
halt was the same as shutting down. On my arch install that uses
systemd halt is like giving your computer a lobotomy. Its still on but
nothing going on.
Personally I suspend my computer all the time unless I need to reboot it
for an update or need to shut it down because of a thunderstorm.
Good question though.
