Linux, with a tiling window manager. :-) You could say that it favors strongly both cases: running windows full-screen and also running a 70% window with say two 15% windows. Windows 10, which I use in work, has this annoying habit that if I maximize browser for a webapp that requires (benefits from) more screen estate, it doesn't always restore to the earlier size correctly. But it's something I can live with.
