Basically, I do lots of things with keyboard shortcuts, so my hand is hovering over the keyboard by default. Which means, it’s just much quicker for me to reach for the touchpad below the spacebar, and particularly also to later move back to the keyboard without having to find my position anew.

I do still find touchpads less precise, but I often accomplish the clicking of buttons via keyboard shortcuts, and mostly need the mouse pointer for dragging or hovering things, which don’t require a ton of precision.
