Games

Precise != Accurate

Using WASD may feel better, but it'll take a lot more work to get into a specific position vs just clicking. By definition, clicking will always be more precise, since you'll go exactly where the chick happened.

As for accuracy, that really depends on the type of game. If you're playing a slow moving game, it probably comes down to how the interaction works (e.g. is it like a CRPG where you need to be near but not on an NPC to talk?), and that's largely preference imo. A fast moving hero game would probably favor WASD since you'd care more about relative movements than absolute movements. An RTS, however, would absolutely favor mouse because you need to make big jumps to move to different squads and whatnot.

For nearly every game where WASD is preferable, I prefer controllers, so WASD is rarely my preferred input option.

Theres also the point that point and click (or analog stick) means you can move directly in an axis that is not possible by WASD, so off the 8 wasd axes, this will be quicker than WASD (although not by THAT much).
