On a similar note, performance is sometimes better. As a direct comparison, the steam version of the Lenovos Legion S handheld is significantly more performant than the windows version. Like 20% better FPS and double the battery life. Literally the only difference between the two is the OS.
Though from what I've read, Microsoft could fix that relatively quickly, if they made some tweaks to Windows (and called it a special 'handheld gaming edition' or so).
For some reason, the Lenovo Legion S's Windows still comes with a lot of baggage and background services etc.
