On my Lenovo sleep works as good as on my older Macbooks. Not having a power saving sleep mode as good as the Macs was one of my main complaints when switching away from Apple. The key to success was the systemd's hybrid sleep mode. With it I can use the Lenovo just as the Macs, that is: never switch off, just close the lid and restart work when I open it again. As a bonus it also properly hibernates when it runs out of battery (just as the Macs do).

Well done - a function works well on a restricted set of hardware which the OS has been tested thoroughly against. How do you expect that same thing to be achieved with the hundreds of potential laptops out there which could run Linux?

Who cares? The tribulations of the creator are not the concern of the end user.

If i can expect a macbook to work properly running macos, but can't expect a laptop running Linux to work properly, that's all I need to know. I'm not going to be all "I guess it doesn't matter that my laptop doesn't sleep, they have hundreds of models to account for!" and just deal with it.

So--mac and linux are equal?
