For pure gaming (ie you're not interested in general computer use) a console would be the best choice (you just stick a compatible game disc in it and away you go - - no technical hardware stuff to consider)
If, however, you want to game and do general computer stuff all on the same machine, then obviously choose a PC.
I'm not saying one is better than the other, it's just a case of which would be more suitable to the individual trying to decide.
