In my experience MacOS users seems to have as much trouble with screens and thunderbolt dock as I do. We had to try nearly all double screens thunderbolt docks on the market and I think we lost hope to find one that works reliably out of the box with those 3 OSes.
I cannot say for battery life, people tend to be connected to power all day here, so that's probably not the reason.
Not even sure what is seamless copy/paste sorry.
But okay, admittedly I don't do anything fancy with my audio devices, or my screen scaling, that must be probably it
I also have issues plugging and unplugging external USB-C displays; I've found that I have to plug them in in reverse order in order to get them to be recognized.
Be that as it may, macOS has some cool display features from Sidecar (plug in an iPad and it becomes a poor man's Cintiq) to the upcoming Universal Access (seamless mouse/keyboard control over multiple devices including drag & drop and cut & paste.)
Seamless copy/paste means that multiple Apple devices can share the same clipboard, so you can copy on one devices and paste on another. Drag and drop is even cooler since you can drag something off an iPad and onto a Mac or vice-versa.
