Battery life and hibernate behaviour is unmatched on a Mac. Nothing else comes close. I’ve never rebooted less.
As for ergonomics it fits my workflow of having lots of virtual desktops and full screen apps open, panning between them with the trackpad. Especially when on a laptop the gesture-based approach feels a lot quicker than picking up a mouse. I'm becoming more and more of a terminal monkey these days so it's less relevant but I'd still recommend them to anyone.
