Macs are the only computers I’ve used that have had close to zero issues with sleep. But I don’t even bother sleeping on the machines running Linux distros: with SSDs, powering on and off is so fast that I just shut the computer down whenever I’m done with it. I should time it to know for sure, but a cold boot to fully operational Firefox window feels like maybe 15 seconds. Powering off is not even five seconds. Not as fast as waking from sleep on my MBP but zippy enough for me.
