You wrongly assumed that your perception of what's "faster" is correct just because it's setup that way by the OS.

> A) Both hands on the keyboard, making it easy to reach both the Win key and the arrow keys at the same time to snap your windows.

It might be "easy" to reach arrow keys, but it's even easier and faster not having to do that

> B) making window snapping instant with the mouse

Your left window slightly overlaps the right one. You want to resize it by reducing its width by ~5% and its height by ~9% to avoid that Name your "instant" list of mouse actions to achieve that.
