I would say that in addition to a usable desktop, Linux distributions generally also provide a more stable Windows environment than Windows itself does. I have quite a suite of games in Steam and GoG, and I find that many older games that simply cannot be coaxed into running on Windows can be made to run happily on one version of Wine/Proton or another.
There are still some weak areas in desktop Linux if you're running a desktop that isn't Gnome or Plasma - wifi configuration comes to mind immediately, as does sound configuration. Bluetooth can be picky if you don't know to get all the non-free firmware.
But really, we're living in a dream era of Linux desktops, if you happen to have lived through the early days of `startx` and XFree86. Hands up if you ever smoked a monitor coil with a bad X config file...
