Optimization. I've always had a good gaming pc with bunch of consoles. When I tried games on both consoles and pc I realize that experience on consoles is better most of the time. While on pc you can get better visuals, better fps etc if you have a powerful one. But on consoles games runs more smoothly with less bugs and glitches. Most games desings for consoles and then ports to pc I think and that's why gaming on consoles may give a better experience to players.

try userbenchmark to see your cpu score and other people's to compare. it's not an effective way to do this but it's fast and easy.
