I have had several Apple devices over the last 20 years and every single one has had the occasional sleep/wake issues. Yes it is generally better but I would stop short of saying Apple has mastered it. I've observed wake failures on all Apple laptops I've owned -- say 1 in every 50 or so wakes will fail. I had one Apple laptop in particular struggle to stay in a sleep state overnight to the point it'd often be completely flat the next morning requiring a cold boot. YMMV but Apple hasn't completely solved the sleep/wake issues in my experience. My Lenovo laptops under Linux and Windows achieve sleep/wake reliability almost as good as Apple/macOS IMHO.
