I have found it to be remarkable over the last few years. I keep coming back to Debian although I've used OpenSuse Tumbleweed in recent times, and some other flavours before that.
With Debian, I've used a very old Dell Latitude (circa 2010, Core2Duo, DDR2, i3wm or XFCE) and newer Dell Inspiron (2017, i5 7th Gen, DDR4, full HD touchscreen display, KDE/XFCE+i3wm) and never had trouble with either sleep/wakeup or with wifi. Touch isn't as great as Windows, so it detects only "left click", not right click, zoom, etc. but I never use touch so it's something I can live with.
Incidentally, I installed Linux because the Windows 10 that came preinstalled had some hardware issue and the fan was always on, so I was getting around 1 hour of battery life. Switching to Tumbleweed (Linux 4.x at that time) gave me amazing battery life, around 5-6 hours. And when Debian 9 (kernel 4.x) got released, I quickly moved to it, and still get around 4-5 hours if I'm doing text editing, browsing and little bit of compiling.
