Serious question. What does the gravitational pull of an object have to do with "landing" on it being harder or easier? Get there, match velocity and trajectory, and slowly descend until you contact, right? and ofc i mean small bodies, not like a planet or a moon.

Once you're there you need enough gravity to actually pull your craft down to the surface. if you intend to do anything on the surface, you need gravity to do [I]anything[/I] without it you have to use explosives and harpoons and other such complicated setups to provide leverage (see rosetta lander and its failure) then without gravity, you have to provide all your deltaV to get back to earth, if an object was sufficiently massive you could use it to slingshot and get free deltaV Gravity makes everything easier
