I personally find whack-a-mole to be a far superior system because of the design and the fact that the characters exist physically. In PC gaming, the characters are only visible on a screen and you are not able to feel them. Also whack-a-mole encourages the use of physical force where as in PC gaming that might DESTROY the puny PC.
In conclusion, Whack-a-mole is better than PC gaming and anyone with an opposing argument is an idiot, and an inbred.
