Not actually subjective. Massively superior to avoid all that unnatural wrist movement, and trackpads enable multi-finger gestures of all kinds that a mouse can't do. Meanwhile you have more precision with much less motion.
And for this particular application, it should be quite easy to see that a mouse requires a mouse pad, and relies on being used in the wrong plane, because of gravity, whereas a trackpad can be anchored, takes up a lot less space, and can be used in any plane.
... no, they aren't? What a weirdly absolute but subjective statement.
