I prefer a trackpad while I work, and the reason is simple: Much less movement to switch from trackpad to keyboard than from mouse to keyboard. And much easier to land on the key you want without looking.
And I very much doubt you’d be faster than me with a mouse!


A gamer does not need to switch from the mouse to the keyboard repeatedly. Plus, a gamer cares about precision, which obviously a trackpad lacks.
“Faster” standalone means nothing. Can you move the pointer faster with a mouse? Of course. But I don’t see most people flicking on their workstation.
In the context of this thread, “faster” refers to completing your tasks faster. And for that a trackpad beats a mouse if your job requires you to type a lot.
