Yes it is. I’ve heard from Hackintosh Overclocker types that Apples ACPI[1] tables are the best and most of the PC motherboard manufacturers are compete garbage. Including WTF how does this hardware even function moments.
I assume things are better these days, but back in 2005 the thing that lead me to switch to mac was seeing a friend with a powerbook which had a sleep mode that actually worked.
I grabbed my (sleeping, lid closed) macbook from my desk this morning. When I pulled the charger to put it into my bag, I started hearing the faint audio of the youtube video I was playing when I closed the lid last night.
Macs today sleep like Windows machines a decade ago
