My considered opinion over three decades of playing video games on PCs, consoles, and other computers, is that consoles are best used for media streaming.
Except these days you can build a budget HTPC which is more powerful and more useful than a console for less than a console.
Oh yeah most of them end up on PC yeah. But its that damn time scale that ticks me off.
As a point made out that Controllers are good for certain things and mouse n keyboard are good for certain things. I use contolers for driving as I dont have a wheel. Also use them for my UFC n Wrestling games.
Oh and a quick off shoot they so need to bring wrastling to the pc. It would be awesome.
