Even Apple struggled to get it working perfectly in my experience across several models in the PPC/x86 era. Yes they are better(-ish) but when I had Apple laptops I'd still see weird sleep/wake issues in around 1 in every ~50 sleep/wake cycles. I also had one Apple laptop which had its battery going from 100% to 0% overnight during sleep requiring a cold start in the morning on a regular basis despite it being put to sleep the evening before and seemingly going to sleep without issues. Lenovo manages to do sleep/wake fine in Linux almost as well as Apple in my experience and I sleep/wake my Lenovo laptop regularly -- this is across two different models I have used so far (X1 and X390). Hopefully Apple has improved this in their ARM laptops but haven't used them much so can't really comment on ARM.
Even now on ARM it's not perfect. my M1 Mini will wake from sleep to a greenscreen and then crash/reboot ~once every few months, irrespective of uptime.
My work mac (M1 Pro) occasionally locks up and reboots when waking from sleep too, at about the same frequency.
Always wondered why this was such a difficult problem to solve, seemingly irrespective of operating system. (Linux has never been acceptable or reliable in this respect, IME, regardless of distro and hardware configuration.)
I've never had an issue with wake/sleep on any of my M1/2/4 devices. The only issue I can ever recall with sleep was the 2019 16" Intel (which had a host of issues).

I'd rate my OpenBSD X1 as not terrible too. Not as smooth as MacBook but adequate.
I always had the suspicion that this has more to do with a lot of kernel hackers using Thinkpads, so they fix them up, rather than Lenovo doing a good job.
It’s much better on ARM. And their external monitor support is so much faster and reliable now. Having control over all their hardware has made a noticeable improvement.
This is not my experience. My M1 Pro MacBook has very strange issues with sound over HDMI. I usually need to reboot it when I connect it to my TV or media won't play if the sound is output over HDMI.
I don't think so. In that state, video will jump and stutter wildly, run very fast, and audio will be very broken. It's not just the sound that's affected.
Which all could be caused by a broken HDMI implementation (refresh, synchronization and audio are all encoded and synchronized).
But of course I could be wrong and every M1 Mac has severe issues connecting to HDMI TV's.
I've tried a recent LG OLED, and a bunch of other TVs at friends and it happens every time if the laptop has been sleeping previously. If it's a fresh boot it never happens. That leads me to believe it's something on the laptop side.
