my friend told me that freebsd does it better ;)
anyway it's just "been told", "somewhere" etc.

to compare things we first need to set up a metric :)

IMHO it depends on hardware and ACPI. maybe linux handles strange cases 
better maybe not.

Simply - install linux, then FreeBSD on same machine and check it :)
