Linux

Windows spends all this time being polite about shutting down, asking programs nicely to close, saving your work, and generally treating everything like a delicate diplomatic negotiation. Meanwhile, Linux just casually kill -9s everything in sight without a second thought. Firefox still running? Gone. Unsaved work? Should've thought about that earlier. Linux doesn't negotiate with processes—it's basically the Terminator of operating systems. The penguin mascot really should be holding a shotgun at all times because that's the energy we're dealing with here.
