Not from my experience. Guess it depends if you play tons on a console and thats all you know.
I'm primarily a PC gamer and I find controllers better for certain games. The new Batman games I think are equally good with both control schemes, but there are other games that are definitely better with a controller. Try a racing game or a platformer with a keyboard and mouse. It sucks.
I got Darksiders from Steam a few months ago and it's much worse with a keyboard and mouse.
