I think the gap that makes Consoles 'inarguably superior' in local multiplayer is going to close rapidly as the steam link's issues get worked out.
But I do agree, Consoles (Specifically Nintendo's) are currently inarguably superior by a wide margin for local multiplayer. And local multiplayer games provide distinct enjoyment that remote multiplayer games cannot replicate effectively.
Steam link is effectively just a way of turning your PC into a more console-like device. But most of us don't have Steam Link or an HTPC, so consoles are more convenient, which has always been the console tradeoff: loss of control for added convenience.
